等离子体中弹丸消融的探讨

STUDY OF PELLET ABLATION IN PLASMAS

本文采用弹丸消融的双区域模型,对弹丸消融过程进行了数值求解。分析Parks的模型,发现其定标律不适合于高温度、低密度的等离子体中弹丸的消融。估计了热电子能量分布函数对消融率的影响。

A numerical calculation is performed using a pellet ablation model with two regions. Analysis of Parks's model shows that his ablation sealing law is not applicable to pellet ablation in plasmas with high temperature and low density. The effect of energy distribution of electrons on ablation rate is estimated.
