本文研究了线性传输方程的数值解法.利用物理的熵函数得到了一种新的Entropy-Ultrabee格式.数值实验表明该格式长时间计算效果非常好,在间断附近有比较高的分辨率.
In this paper,we investigate the numerical solutions for linear advection equation.A new Entropy-Ultra-bee scheme is obtained by using physical entropy function.Numerical experiments show that the scheme has a very good quality in long-time numerical computation and has high resolution in the vicinity of continuities.
