Fluent 多组分流最多只能达21组分,谁有高招
如果你用的是Eulerian方法,那你这么多的组分而且激波?这么说,你的流体中包括可压缩流体了?要知道FLUENT中的Eulerian法现在还做不到可压缩流体的计算。如果是Eulerian法,则组分的限制的确是由内存决定的。另外,并行计算对用户的要求也很高。
以下是FLUENT帮助手册中的一段说明,关于组分数的:
With the Eulerian multiphase model, the number of secondary phases is limited only by memory requirements and convergence behavior. Any number of secondary phases can be modeled, provided that sufficient memory is available. For complex multiphase flows, however, you may find that your solution is limited by convergence behavior. |
