任意欧拉-拉格朗日耦合框架下三维非定态可压缩流体流动的数值模拟

Numerical modeling of three dimensional and time dependent compressible fluid flow with an arbitrary Lagrangian Eulerian

在欧拉与拉格朗日耦合的框架下，利用有限体积法对非定态三维可压缩流体流动问题给予研究，开发了一般网格下的通用计算程序 该程序适用于计算复杂几何边界条件、运动边界条件等情况下流体流动问题 作为例子，计算了简单中间包内流体的流动情况，给出了随时间变化的流场分布

Three dimensional,time dependent,compressible fluid flow problems have been studied with the finite volume scheme based upon an arbitrary Lagrangian Eulerian scheme.A general program for arbitrary mesh has been developed.This program can be used to the fluid flow with arbitrary shape boundary condition and moving boundary condition.As an example,the fluid flow in a simple tundish is calculated,and the time dependent fluid flow distribution is given out.
