介绍基于流体体积分数的混合型多介质流体守恒的数值模型,该模型的主要思想就是跨过界面速度和压力保持一致.将RKDG方法应用到此数值模型,求解Stifferened Gas状态方程Riemann问题,并推广至由Mie—Gruneisen状态方程表示的真实材料的更一般情形的状态方程的Riemann问题.本文给出了一维、二维算例,数值结果表明该方法是一种高分辨率的方法,可以有效的处理接触间断,激波等物理问题.%This paper gives an introduction to the numerical model of hybrid multi - fluid conservation based on the volume of fluid. The underpinning idea of this algorithm is to assume that both the pressure and velocity are constant across the interfaces. RKDG is applied to this numerical modeh The purpose is to find out the solution to Riemann of Stifferened Gas state equation and to Riemann of the general state equation based on true material and represented by Mie- Gruneisen state equation. This study provides one -dimension and two -dimension numerical examples. The numerical result shows that this method is of high resolution. It is effective in handling physical problems such as contact intermission and shock wave.
