MULTI2D – a computer code for two-dimensional radiation hydrodynamics

Abstract
Simulation of radiation hydrodynamics in two spatial dimensions is developed, having in mind, in particular, target design for indirectly driven inertial confinement energy (IFE) and the interpretation of related experiments. Intense radiation pulses by laser or particle beams heat high-Z target configurations of different geometries and lead to a regime which is optically thick in some regions and optically thin in others. A diffusion description is inadequate in this situation. A new numeri...

Nature of problem
In inertial confinement fusion and related experiments with lasers and particle beams, energy transport by thermal radiation becomes important. Under these conditions, the radiation field strongly interacts with the hydrodynamic motion through emission and absorption processes.

摘要：本项研究旨在开发二维空间中的辐射流体动力学模拟，尤其关注间接驱动惯性约束能源（IFE）的目标设计和相关实验的解释。通过激光或粒子束产生的强烈辐射脉冲加热不同几何形状的高Z靶配置，导致某些区域光学上较厚，而其他区域光学上较薄。在这种情况下，扩散描述是不充分的。一项新的数值方法被提出以处理此类问题。
程序名称：MULTI2D
目录ID：AECV_v1_0
问题性质：在惯性约束聚变及其与激光和粒子束相关的实验中，热辐射的能量传输变得重要。在这些条件下，辐射场通过发射和吸收过程与流体动力学运动产生强烈相互作用。
