2D numerical simulation of laser ICF

The numerical simulation of Inertial Confinement Fusion (ICF) is very difficult because ICF involves many problems such as extremely high temperature and pressure, multi-materials, large deformation, strong non-linearity and strong discontinuity. LARED-H, a 2-dimensional 3-temperature radiation hydrodynamics program, is developed to study laser ICF. Based on multi-block structured and patched grid, LARED-H can deal with complicated geometry or material distribution. Some numerical results are obtained by using LARED-H to simulate laser ICF. The results are rational qualitatively, some physical quantities are in good agreement with experiment, the mesh movement and radiation temperature also approach the results by LASNEX. These show that the algorithms and program of LARED-H are valid and correct. (authors)
