Abstract : 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
文摘: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
