Postdoctoral Position in Numerical Simulation of Radiative-MHD

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


The group of Prof. Dr. Li Ben-Wen, in Institute of Thermal Engineering, School of Energy & Power Engineering, Dalian University of Technology (DUT), has a long time and wide experience in researching thermal radiation, and its combinations with others, like, conduction, convection, combustion, and magnetohydrodynamics (MHD), and especially 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 for 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 the experienced scholar, who is an expert in CFD with DNS, is available.

The main task of the postdoc will be the numerical simulations of transition or turbulent Radiative-MHD in a cylinder or rectangular enclosure. The numerical methods can be the Finite Difference method, the Finite Volume method, but the Spectral method will be a 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 transition to the spectral code 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 code transition is necessary to reduce computer costs 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.

As for thermal radiation, we have accumulated lots of codes based on spectral methods or discrete ordinates methods (DOM).
Work office and personal computer are provided. The computer center will provide a 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 an apartment with a bath and cook, but cheap rent.
Dalian is the most beautiful city in north-eastern China, and the communications in domestic and international are very fast and convenient.

The 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.

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.
