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:在歐拉與拉格朗日耦合的框架下,利用有限體積法對非定態(tài)三維可壓縮流體流動問題給予研究,開發(fā)了一般網(wǎng)格下的通用計算程序.該程序適用于計算復(fù)雜幾何邊界條件、運動邊界條件等情況下流體流動問題.作為例子,計算了簡單中間包內(nèi)流體的流動情況,給出了隨時間變化的流場分布
