摘要: 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。分析其数值实验的结果来研究人为粘性在超新星爆发计算中所起的作用

关键词: 超新星爆发, 人为粘性

Abstract: 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.
