Abstract

Abstract

The process of nonequilibrium radiation ablation of CH foil has been numerically studied using 1D RDMG code of multigroupnonequilibrium radiation hydrodynamic under the condition of radiation source of ShenguangII hohlraum，meanwhile different ablation images from the process of nonequilibrium radiative ablation and the relative scaling laws are obtained. Numerical results show that both electron temperatue and ion temperature separate from radiation temperature and the spectra of radiation flux is nonequilibrium inside CH during the whole process of CH foil ablation. The ablative depth is shorter and shock wave is weaker compared with equilibrium ablation because nonequilibrium radiation ablation contains ionization wave, radiation heating wave and radiation ablation wave.
