Hello everyone...
I am trying to compute double square impinging jet with LES WALE model. Because I have two jets with different temperatures, I decided to compute this solution as compressible flow. (anyway the inlet velocities are 5 and 8 m/s) As the title says, am using buoyantPimpleFoam... Does enybody have an idea why I get so funny velocity field in the channels and why the velocity later explodes and the calculation diverges? I am thankful for any kind of suggestions |
