在实验室及工业尺度，热辐射对流体力学以及磁流体力学Rayleigh-Bénard热对流终极制度转变规律影响研究还未见报道，也很难进行实验研究。然而，随着可再生清洁能源的大力开发和广泛应用，比如太阳能利用中的微纳米流体、电化学能存储液态金属电池中的熔融盐电解质等，都与辐射流体力学或辐射磁流体力学密不可分。采用直接数值模拟方法，分别探究辐射流体、辐射磁流体Rayleigh-Bénard热对流的一般规律以及热辐射对Rayleigh-Bénard终极制度转变规律的影响，并在此基础上实验研究液态金属电池内流体流动不稳定性影响因素以抑制方法。毫无疑问，本研究具有重要学术意义和实际应用价值。

In the scale of experimental and industrial, there is no report about thermal radiative effects on hydrodynamic or magnetohydrodynamic Rayleigh-Bénard ultimate regime transition, and it is difficult to conduct experiments. However, with the development and wild application of renewable clean energies, e.g., the micro/nano-fluids in solar energy utilization system, the molten salts in electrochemical-based liquid metal batteries, they are all tightly related to the radiative hydrodynamics or radiative magnetohydrodynamics. Using direct numerical simulation, we will research many laws of radiative hydrodynamics or radiative magnetohydrodynamics, and the thermal radiation effects on Rayleigh-Bénard ultimate regime transition, respectively. Based on these, the influencing factors of fluid instabilities in liquid metal batteries and the suppressing techniques will be investigated experimentally. Certainly, this project is important and meaningful for science and practical application.
