介绍了辐射流体力学程序LARED集成程序的物理背景、模型方程、数值方法和数值算例。该程序主要应用于激光间接驱动惯性约束聚变的二维整体模拟,兼顾激光直接驱动、辐射驱动靶丸内爆过程和流体不稳定性等物理过程的数值模拟。通过与实验数据、一维辐射流体力学程序进行比对,验证了程序的可靠性。该程序实现了多群输运建模下NIF点火靶的全过程数值模拟,并已应用于惯性约束聚变的物理研究。 The physical background, model equations, numerical methods and numerical examples of LARED integrated program of radiation hydrodynamics program are introduced. The program is mainly applied to the two-dimensional global simulation of inertial confinement fusion of indirect laser driving, taking into account the numerical simulation of physical processes such as laser direct driving, radiation-driven shot blasting and fluid instability. By comparing with experimental data and one-dimensional radiation hydrodynamics program, the reliability of the program is verified. The program realizes the whole process numerical simulation of NIF ignition target under multi-group transport modeling and has been applied to the physics research of inertial confinement fusion.
