摘要: 针对Mie-Grüneisen状态方程下的多介质流场,将Euler方程中的部分复杂参数作为守恒量引入到新的方程中,使原方程结构得到简化.同时引入质量分数以表示流场中不同介质的变化,并对通量作近似处理,再利用MUSCL-TVD格式结合改进过的Euler方程进行求解,模拟Mie-Grüneisen状态方程下多介质相互作用的情况.结果表明,通过本方法既能使方程组满足守恒,又能较好地处理多种介质形成的间断面.

Abstract: For multi-component fluid field under Mie-GrÜneisen equation of state,we consider some complex coefficients in Euler equations as conserved variables,and add new equations to simplify structure of original equation.In addition,mass fraction is introduced for different medium in field and flux is treated approximately.With modified Euler equation system and a MUSCL-TVD scheme we simulate interaction of different medium characterized by Mie-Graneisen equation of state.It shows that the approach makes the equations conserved and treats sharp interfaces with different medium well.

Key words: multi-component, mass fraction, Mie-Groneisen, conserved
