摘要
对二维Euler方程给出一个二阶精度的有限体积方法 ,方法的主要思想是把Euler方程的一个时间步分两步计算 :第一步只考虑压力加速效应 ,第二步再考虑输运效应 ,离散过程中采用一种线性重构函数以计算交界面的流通量 ,数值实验表明该方法是非常有效的 .
In this paper,we have constructed a second order accuracy finite volume sheme on Euler equations,the new scheme consist of two steps for each time step: the first step we take into account the effects of acceleration caused by pressure gradients,and the second step transport effects are computed. A non-oscillatory linear reconstruction of flow variables is applied, the result of numerical experiment is satisfactory.
