研究了辐射流体力学中流体流动中的辐射传递。研究了辐射条件下的动力学规律。实际辐射流体动力学过程复杂，数值模拟是主要的研究手段之一。在数值模拟中经常使用分裂法，其中流体运动和辐射是分开计算的。我们讨论了辐射扩散计算中的计算问题。研究了严重变形网格的扩散格式和非线性迭代方法。简要介绍了研究进展。
Radiative transfer in fluid flow of radiation hydrodynamics is studied.Kinetic laws under radiation condition are investigated.Practical radiation hydrodynamics process is complicated,and numerical simulation is one of primary research means.Splitting methods are often used in numerical simulation,in which fluid motion and radiation are computed separately.We discuss computational problems in radiation diffusion calculations.Diffusion schemes and nonlinear iterative methods on severely distorted meshes are studied.A brief introduction on research progress is given.
