NUMERICAL EXPERIMENTS OF ARTIFICAL VISCOSITY WITH RESPECT TO COMPUTATING SUPERNOVAE EXPLOSION

通过对同一个前身星模型“ＷＷ８８”，选取三种基本不同形式的人为粘性项的八种不同的情况，作超新星坍缩和爆发的全过程的数值模拟。

In terms of the three basic forms and the eight various cases of artifical viscosity for the same progenitor madel “WW88”, the numerical simulation has been performed for the whole processes of collapse and explosion of supernovae, and the artifical viscosity influences on compulation of supernovae explosion are investigated through analysis of numerical experimental results.
