基于Fluent的绕流问题的数值模拟与并行计算

Numerical simulation and parallel computation of flow over object using Fluent

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。

Two numerical cases of the same two dimensional incompressible flow fields were computed with different number of cells. Both of these two cases were computed in parallel manner and serial manner. Comparison shows that when the number of cells is big enough, the efficiency of parallel computation is obviously better than serial computation, but this is not true when the number of cells is small. The purpose is seeing about the parallel computing ability of the Fluent and providing technical reference to cosmically engineering application computing.
