Hi everyone,
my name is Gao. I am now using staggered grid SIMPLE to simulate gas exchange. I have successfully simulated gas flow at low speed (Mach<0.3).When I increase the speed, the results are not reasonable. I have searched some literature and there are some collocated grids with SIMPLE at high speed. But I want to know, it is possible to use staggered grid SIMPLE at high speed. If you can give me some advice, I will be very grateful for your help. |

High Mach flows should be approached using density-based formulations. Usually, non-staggered grid is used. |
