  1. pamir 2024

The next Conference “pamir” will be organised in September 2024 from 16th to 19th in collaboration between the University of Cagliari Italy, the Universities of Grenoble together with the CNRS, and the CEA Cadarache. After being held in different countries in previous years, the Conference returns to France – close to the very location where the first edition of pamir was held in 1991, also with the first participation of Latvian scientists.

This is why the organisers have chosen the location in the proximity to CEA-Cadarache Research Centre, — the Mileade Village club at Carry le Rouet: on the shore of the Blue Coast, Mediterranean Sea, near Marseille.

This will also give the opportunity to visit the facilities dedicated to Fission and Fusion.

The Conference will be combined with the Summer School that will be given on various topics, mainly related to energy.

The exact dates of the event will be given later:  all the information concerning both the “pamir 2024” Conference and the Summer School will be available on the website EU MHD society: https://eumhd.com/

Job description

Research Fellow in Computational Magnetohydrodynamics on Nonlinear low states and turbulence produced by helical magnetorotational-type instabilities funded by the Science and Technologies Facilities Council STFC (Coventry University, UK)

Fixed term (end date 31st August 2025)

Applications are invited for the position of Research Fellow in Computational Magnetohydrodynamics sponsored by the Science and Technologies Facilities Council (STFC) (https://stfc.ukri.org).

The project is concerned with the development of a comprehensive nonlinear theory of helical magnetorotational

instability (HMRI) which could explain the origin of turbulence in hydrodynamically stable astrophysical

flows not affected by standard magnetorotational instability (SMRI).

Helical magnetorotational instability is thought to be important for the dynamo action in the solar tachocline – a thin transition region with a thickness of ~0.04R⊙ separating the rigidly rotating radiative zone of outer radius 0.7R⊙ from the convective zone which rotates faster at the equator and slower at the poles. The rotation rate increasing radially outwards in the equatorial part of the tachocline suppresses the SMRI but not the HMRI which can still be effective in this dynamically important solar region. However, unlike the SMRI, the HMRI, according to the underlying linear stability theory, is limited to relatively slow rotational flows. The ability of the HMRI to destabilize highly inertial flows outside its linear instability range is unclear. Solving this theoretically challenging and astrophysically important problem is the main aim of this project which involves a state-of-the-art theoretical study combining weakly nonlinear analysis with the fully nonlinear finite-amplitude solutions and direct numerical simulation of HMRI-driven turbulence.

The successful candidate should hold a PhD or equivalent degree in Computational Fluid Dynamics, Magnetohydrodynamics or Physics with a proven track record of producing a high-quality scientific output.

The Research Fellow will work within the vibrant environment of the Fluid and Complex Systems Research Centre, at Coventry University. The group conducts both fundamental and applied research in the fields of stability, magnetohydrodynamics, turbulence and geophysical fluid dynamics as well as other areas of fluid mechanics. In the REF2014, 84% of the group’s output, as part of the mathematics submission, was deemed ‘internationally excellent’ or ‘world-leading’.

The post is fixed term until 31st August 2025. To apply please also include your CV with a publication list. For further information please contact Dr Janis Priede (Coventry University, j.priede@coventry.ac.uk, +44(0)7557425329).

Dear colleagues,

We are looking to recruit a postdoc to work with Dr Céline Guervilly and Dr Graeme Sarson on a STFC-funded project on the dynamics of stably-stratified layers in planetary cores. The project concerns double-diffusive convection and will incorporate the effects of rotation, spherical geometry and magnetic fields. The goal is to explain how a stably-stratified layer located at the top of the core shapes the magnetic field observed at the surface of the planet. The position is based at Newcastle University and is funded for three years with a flexible start date.

Applications close 5th April 2022. Further details can be found at:

Postdoctoral Position in Numerical Simulation of Radiative-MHD

(from Prof. Ben-Wen Li, Dalian, China)

 

INTRODUCTION
The group of Prof. Dr. Li Ben-Wen, in Institute of Thermal Engineering, School of Energy & Power Engineering, Dalian University of Technology (DUT), has long time and wide experience in researching thermal radiation, and its combinations with others, like, conduction, convection, combustion, and magnetohydrodynamics (MHD), and specially engaging in the numerical simulation. Recently, we obtained the NSFC (National Natural Science Foundation of China) project, titled “Research of Thermal Radiation Effects on Magnetohydrodynamics Instabilities” with granted No. 51976021 (Jan. 2020 till Dec. 2023). We are applying more projects. We have accumulated lots of home designed codes for pure thermal radiation (with participating media in 3D Cartesian coordinate systems and 2D cylindrical ones), radiation-conduction, radiation-hydrodynamics and radiation-MHD (spectral methods but with limitation of laminar flow). Meanwhile, lots of journal papers have been published. Based on the NSFC project, we are preparing experimental research and also numerical simulations, especially for laminar to turbulent transition. In such cases, a full postdoc position for experienced scholar, who is expert in CFD with DNS, is available.

RESPONSIBILITIES
The main task of postdoc will be the numerical simulations of transition or turbulent Radiative-MHD in cylinder or rectangular enclosure. The numerical methods can be the Finite Difference method, the Finite Volume method, but the Spectral method will be priority. At present, the MHD will be limited to quasi-steady cases (the magnetic Reynolds number is far less than unit). For thermal radiation, we expect the full RTE (radiation transfer equation) solution with help of Prof. Li Ben-Wen (many home hold codes using spectral methods). The main challenges may exist in the spectral codes transition from MMT (matrix multiplication transition) versions to FCT/FFT (fast cosine transformation/fast Fourier transformation) versions, the turbulent radiation interaction (TRI), and the instabilities analysis. The codes transition is necessary to reduce computer cost for instabilities and turbulent flow. The spectral methods are necessary to keep the higher accuracy. Based on the simulations, more phenomena/disciplines can be observed/discovered for radiative MHD.
Based on our former works, you will be supervised by Prof. Li Ben-Wen, and collaborating with Ph.D. students. You can guide Ph.D. students both in experiments and simulations, especially the DNS and instability analysis. Your creativity is welcome and expected during the research process.

CONDITIONS
As for thermal radiation, we have accumulate lots of codes based on spectral methods or discrete ordinates method (DOM).
Work office and personal computer are provided. The computer center will provide computation source for large computation, and the computation cost will be paid from the project.
The salary per year is ¥300,000RMB before tax, about $46,470. Our university can provide apartment with bath and cook, but cheap rent.
Dalian is the most beautiful city in the north-eastern China, and the communications in domestic and international are very fast and convenient.

PROFILE
Candidate should have a PhD degree in Physics or Engineering (or equivalent), with demonstrated experience in CFD in fluid mechanics, or thermo-hydrodynamics, or even in MHD.

OFFER
We offer the open, stimulating and multi-disciplinary research environment. The duration of the contract will be 2 years. After evaluation, it will be possible to extend another 1 year.

International conference ELECTROMAGNETIC PROCESSING OF MATERIALS 2021 will take place in Riga Latvia on June 13-17, 2021.

Electromagnetic Processing of Materials (EPM) relates to all branches of materials processing where some benefit could be attained from an electromagnetic influence on the process. This covers traditional areas such as liquid metal processing, metal casting and solidification, induction heating, but also crystal growth from the melt, plasma processes, recycling, separation. The series of EPM conferences was initiated in 1994 by S. Asai (Japan) and M. Garnier (France). It takes place every three years alternating between Europa and Asia (Nagoya 1994, Paris 1997, Nagoya 2000, Lyon 2003, Sendai 2006, Dresden 2009, Beijing 2012, Cannes 2015, Hyogo 2018). The conference is open for any kind of materials processing involving electric or magnetic fields. It intends to bring together people from academic institutions, industry and related equipment manufacturers.

We are looking forward to welcoming you to Riga 13-17 June 2021.

IV. PhD on the Transition to Turbulence in Particulate Pipe Flows (Coventry, UK)

(from Alban Potherat, UK)

———————

 

A PhD position in experimental fluid mechanics is open at the Centre for Fluid and Complex Systems (FCS), Coventry University, in collaboration with Oxford University, under the joint supervision of Prof. Alban Pothérat, (Coventry University, UK, http://users.complexity-coventry.org/~potherat/ ) and Prof. Tom Mullin (Oxford University).

The topic concerns the experimental study of pipe flows seeded with particles. At high enough flowrates, flows of liquids in pipes become turbulent. The transition process involves complex nonlinear mechanisms that are still not fully understood. Yet predicting, delaying or triggering – in other words controlling –  the onset of turbulence is a pressing need both as one of the fundamental challenges of fluid mechanics and for the vast range of practical problems where the radically different energy and pressure losses incurred in laminar or turbulent flows have drastic consequences.

A more recent angle to this problem emerged with the growing practical importance of flows seeded with particles that can either prevent or induce a transition to turbulence depending on their size and concentration.  The underlying mechanisms were unknown until recently. The centre for Fluid and Complex systems developed a fully transparent pipe flow device of hitherto unmatched accuracy fitted with a unique optical detection device capable of mapping the motion of fluid and particles simultaneously to make the first breakthrough in this problem of fundamental importance. The question now is to understand how the motions of fluid and particles interact in detail, ultimately manipulate this interaction with electric fields and control the transition.  This is precisely the objective of this PhD, that offers a unique opportunity to use and develop cutting edge experimental techniques to tackle one of the great challenges of nonlinear physics, for both fundamental and practical purposes.

The fluid and Complex Systems Research Centre (https://www.coventry.ac.uk/research/areas-of-research/centre-for-fluid-and-complex-systems) gathers fluid dynamicists, physicists and engineers to tackle fundamental, but also real-life problems involving fluids and complexity with mathematical rigour. For example, aside from its more traditional forte in fluid dynamics and statistical physics, the centre is also developing novel approaches in engineering fluid mechanics, flow measurement and socio-physics. The Fluid Dynamics Group currently comprises 15 Staff and PhD students and runs projects combining theory, numerical simulations and experiments, supported by a number of grants from research funding bodies (EPSRC, The Leverhulme Trust, the Royal Society…) and international partnerships. The group forms part of Coventry University’s Mathematics Unit of Assessment (10) for the Research Excellence Framework. 87% of the submission’s output was deemed internationally excellent at REF 2014. The centre prides itself in its active integration of PhD students in its academic life (events, seminars, interaction with its staff) and provides a vibrant international and interdisciplinary environment conducive to the production of world-class research.

Candidates must hold, or be on course for a 1st class Bsc. or Msc. degree in engineering or physics, with previous experimental experience and be motivated to conduct technically advanced experimental projects. Experience in fluid mechanics and/or measurement technology is strongly advised. The position is for a period of 3.5 years and is expected to start in January 2021.

To express interest in this PhD opportunity, please send a CV and a full transcript of academic records to Alban Pothérat (Coventry University, alban.potherat(at)coventry.ac.uk). Informal enquiries are encouraged.

2.  RESEARCH FELLOW POSITION IN THEORETICAL FLUID MECHANICS AT COVENTRY UNIVERSITY (UK)

—————————–

Location: Coventry Placed On: 2nd August 2019
Salary: £32,243 to £40,802 per annum Closes: 2nd September 2019
Hours: Full Time Job Ref: REQ007193
Contract Type: Permanent

A Research Fellow position in theoretical fluid mechanics is offered at Coventry University (UK). The project concerns convection under a magnetic field in the so called “tangent cylinder” region of the Earth’s core. Much of the mystery surrounding the Earth’s dynamics (its magnetic field, plate tectonics) lies in the nature of the convective patterns within the Earth’s liquid core, and in particular in the region called the “Tangent Cylinder”. What are the possible convective states under the combined influence of the Earth’s rotation and magnetic field, and how erratic are they? This study is part of a theoretical and experimental research program funded by the prestigious Leverhulme Trust (http://www.leverhulme.ac.uk), that aims at answering these questions. The purpose of this thesis is to theoretically predict the possible nonlinear convective states for the first time. We will then evaluate which of these states are mostly likely to underpin the Earth’s core convection.

The Research Fellow will conduct the theoretical and numerical analysis of the problem under the joint supervision of Prof. Alban Pothérat (http://users.complexity-coventry.org/~potherat/index.html) and Dr Chris Pringle.  The study will seek the possible structure of convection by means of advanced stability theory and branch tracking method, to unveil the possible states. In the frame of the research programme, the work is purely theoretical/numerical and will be conducted in collaboration with an experimental study that will seek to reproduce and visualise these non-linear states in an experimental model of the Earth Core.

Successful candidates are expected to hold a PhD in fluid mechanics or a related discipline and to have demonstrated excellent abilities in mathematics and programming.

The successful candidate will be part the vibrant team of internationally recognised academics and PhD students forming the fluid dynamics group within the Applied Mathematics Research Centre, whose work has been ranked at 83% world-class at the UK’ latest Research Excellence Framework in 2014. This unit is part of the Fluid and Complex Systems Research Centre, and specialises in theoretical and experimental fluid mechanics. It is especially renowned for its work on magnetohydrodynamics (MHD), turbulence, stability and geophysical flows. The group closely collaborates with partner groups in world-leading institutions in Australia, China, France, Germany and the UK.

Informal enquiries are welcome: please forward a CV and academic records to Prof. Alban Pothérat (alban.potherat@coventry.ac.uk).

Exploring the origins and evolution of magnetic fields in planets, stars and galaxies, this book gives a basic introduction to magnetohydrodynamics and surveys the observational data, with particular focus on geomagnetism and solar magnetism. Pioneering laboratory experiments that seek to replicate particular aspects of fluid dynamo action are also described. The authors provide a complete treatment of laminar dynamo theory, and of the mean-field electrodynamics that incorporates the effects of random waves and turbulence. Both dynamo theory and its counterpart, the theory of magnetic relaxation, are covered. Topological constraints associated with conservation of magnetic helicity are thoroughly explored and major challenges are addressed in areas such as fast-dynamo theory, accretion-disc dynamo theory and the theory of magnetostrophic turbulence. The book is aimed at graduate-level students in mathematics, physics, Earth sciences and astrophysics, and will be a valuable resource for researchers at all levels.

  1. PHD ON ALFVEN WAVES AND MAGNETOHYDRODYNAMIC TURBLUENCE AT GRENOBLE UNIVERSITY/CNRS/COVENTRY UNIVERSITY

—————————–

(from Alban Potherat, Coventry, UK )

Under the joint supervision of Alban Pothérat, (LnCMI Lab/CNRS and Coventry University) (http://users.complexity-coventry.org/~potherat/), Laurent Davoust (Grenoble-INP, SIMAP Lab) and François Debray (LnCMI/CNRS).

Applications are invited for a PhD (possibly including an MSC internship) in experimental fluid mechanics at the LNCMI-G (Grenoble High Magnetic Field Laboratory, http://lncmi.cnrs.fr/?lang=en). The topic concerns the experimental study of turbulence in liquid metals in a very high magnetic field. Turbulence is one of the major challenges of classical physics. Here, we seek to understand the role played by the propagation of magneto-mechanical waves (called Alfven waves) in the statistical and dissipative properties of turbulence and in its transition between two- and three-dimensional states. This type turbulence plays a key role in the dynamics of a number of astrophysical, geophysical, amongst which stellar accretion disks, planetary interiors but is also suspected to appear in engineering problems such as the cooling of nuclear fusion reactors. Until now, Alfven waves have been difficult to reproduce in laboratories because of the extreme conditions in which they appear (high Reynolds numbers and/or high magnetic fields).

The PhD student will be conducting an experimental project during which a turbulent flow is generated within a experimental device filled with liquid metal and placed inside of one the large magnets available at LNCMI in Grenoble, which are capable of producing some of the strongest magnetic fields in the world. In the extreme fields available at LNCMI, the electromagnetic force becomes propagative on the top being diffusive (propagation of Alfvén waves). The goal of this PhD is to use this unique combination of features to reproduce in the laboratory some of the mechanisms that occur in astrophysical or planetary systems and in the context of nuclear energy production, so as to understand them in detail.

The flow will be diagnosed by means of advanced metrology techniques such as ultrasound velocimetry and electric potential mapping. The PhD student will be in charge of running and improving the experimental device, interpreting the results so as to better understand the observed flow regimes. The combination of extreme magnetic fields and this unique experimental device developed by our joint team in Coventry and Grenoble offers for the first time a possibility to extensively map astrophysical and planetary phenomena that have been extremely difficult to probe direclty until now.

Applicants are required to hold, or be on course for an MSc in fluid mechanics or related speciality (Mathematics or Physics). To apply please forward complete academic records and CV to Alban Pothérat (Coventry University, alban.potherat(at)coventry.ac.uk, +44(0)2476 88 88 65), Laurent Davoust (Grenoble-INP, +33(0)476825206, Laurent.Davoust(at)simap.grenoble-inp.fr ) or Francois Debray, LNCMI (francois.debray(at)lncmi.cnrs.fr, +33(0)476 88 12 44).

  1. MSc+PhD ON MAGNETOCONVECTION BEYOND THE CHANDRASEKHAR LIMIT

—————————–

(from Alban Potherat, Coventry, UK )

Under the joint supervision of
Alban Pothérat, (Coventry University, UK, http://users.complexity-coventry.org/~potherat/),
Jörg Schumacher (Technische Universität Ilmenau, Germany, https://www.tu-ilmenau.de/tsm/ ),
François Debray (LNCMI/CNRS Grenoble, France, http://lncmi-g.grenoble.cnrs.fr/)

A PhD position in experimental fluid mechanics is open at the High Magnetic Field Laboratory in Grenoble (CNRS/ France). The topic concerns the experimental study of Rayleigh-Bénard convection under the influence of high magnetic fields. This type of convection plays a crucial role in numerous natural and industrial processes: for example in the tachocline layer of the Sun, in the liquid core of the Earth, but also in material processing such as the pulling of silicon ingots or the continuous casting of metallic alloys. In general, magnetic fields introduce a dissipative mechanism through the Joule effect which tends to damp, or even suppress convection. This has an impact on characteristic patterns that form in a convective flow. Chandrasekhar (Physics Nobel Prize 1983) derived the theoretical value of the critical Rayleigh number beyond which convection survives for a given magnetic field in the ideal case of a fluid layer confined between two infinite planes. Nevertheless, when lateral walls are present, convective plumes could potentially persist below this limit and thus locally promote enhanced heat fluxes.

This effect has, until now, never been observed in the laboratory, partly because typical electrically conducting fluids are opaque and thus hard to probe. The purpose of this PhD project is to observe the impact of strong magnetic fields on the formation of convective structures and to characterise these states and their possible transition into turbulent convection. For this, the student will be taking advantage of a new technique recently developed by the groups in Coventry and Grenoble, which consists of using a weakly conducting but transparent electrolyte placed in very high magnetic fields. This technique makes it possible to obtain precise maps of the velocity fields by means of advanced optical measurement methods using laser imaging technology (such as Particle Image Velocimetry or Laser Doppler Anemometry).

The PhD student will be in charge of this experimental project and will collaborate with theoreticians from TU Ilmenau in Germany who will be conducting numerical simulations of this problem in parallel, to compare the results.

Candidates must have a master degree in engineering or physics (300 ECTS credit points) and be motivated to conduct technically advanced experimental projects. Experience in fluid mechanics and/or measurement technology is welcomed. The PhD will benefit from a Co-tutelle between Coventry University (UK) and TU Ilmenau (Germany) leading to a PhD award in each university. The work will be physically based in the laboratory in Grenoble (France) for most of the time with extended stays at sites in the UK and Germany. The position runs for a period of three years and is expected to start in spring 2019.

To apply, please send a CV and a full transcript of academic records to:
