摘要: 本文以求解Burgers方程的守恒型Samarskii格式为基础,构造了一组新的分组显式格式。讨论了方法的线性化稳定性。数值结果表明,对于大Reynold数问题本方法明显优于Evans[2]的分组显式方法。

Abstract: A new group explicit scheme for solving Burgers equation is constructed by the conservative Samarskii scheme. The linear stability of this method is discussed. Some numerical examples are given which illustrated that the present method is more suitable than Evans's method for solving Burgers equation with a large Reynolds number.

Key words: Burgers equation, group explicit scheme, stability, Samarskii scheme
