摘要: 以解析离散法为基本出发点,建立任意阶精度的导数逼近关系式,融合Roe的通量差分分裂方法和高精度通量限制器midmod。从而构造成高阶精度的高分辨率、无波动激波捕捉方法。Burgers方程和Euler方程的计算结果表明该方法是一种十分有效的高精度激波捕捉方法,并且计算量与TVD格式相比没有明显增加

关键词: 解析离散法, Burgers方程, Euler方程激波, 捕捉方法

Abstract: A derivate's formula is presented based on the analytical discrete method and can achieve arbitrary order of accuracy firstly.It is combinated with Roe's flux differential splitting technique and high accuracy flux filter midmod,to construct a kind of nonoscillatory shock-capturing method with high order of accuracy and high resolution.

Key words: Analysical Discrete Method, Burger's equation, Euler's equation, Shock Capturing Method
