摘要:使用商用软件 Fluent 对二维不可压流问题进行了两次实验,两次实验的网格数相差很多,发现当网格数少的
时候,并行计算反而不如单机的效果好;而当网格数足够大的时候,并行计算就显示出其优越性来, 目的在于考察
Fluent 软件的并行计算能力,为进行大规模工程应用计算提供技术参照。

Abstract:Two numerical cases of the same two dimensional pressible flow fields puted with different number of cells.
Both of these two cases puted in parallel manner and serial manner. Comparison shows that when the number of cells is big en-
ough, the efficiency of putation is obviously better than putation, but this is not true when the number of cells is
small. The purpose is seeingabout the puting ability of the Fluent and providing technical reference to cosmicallyengineering
puting.
Key words:fluent; parallel fluent; pressible flow; numerical simulation; putation
