| 摘 要： | 应用带有Isobaric修正的GhostFluid方法配合LevelSet方法计算可压缩双介质无粘流动.该方法可以消除计算流体界面时所产生的数值跳动和耗散,且编程上比界面跟踪法简单.应用WENO格式数值求解欧拉方程和LevelSet方程,对由刚性气体状态方程所支配的一二维双介质流动进行数值计算,得到了分辨率较高的计算结果.

| Abstract: | Compressible two-fluid inviscid flow is computed by the Ghost Fluid method with Isobaric fix.The method can avoid numerical oscillation and smearing as is encountered with a shock-capturing scheme in computing fluid interface,and it is simpler to code than fronttracking techniques.The system of the Euler equations which describes the fluid flow and the level set equation which describes the interface motion is solved by high-resolution WENO finite difference scheme.Satisfatory results are obtained for several 1D and 2D compressible two-fluid flows subject to the stiffened equation of state. |
