Dear al,
I am currently trying to simulate supersonic flow. But wall numerical oscillations occur using rhoCentralFoam and dbnsTurbFoam solvers. Numerical oscillations are still present for dense grid first layer heights up to 1e-6m.Boundary condition reference tuts case setting. The same problem is also found in another case of a Scramjet engine. Because the file is too large（5mb）, it can be emailed to you. I need to know the cause of oscillations and how to eliminate them. Thanks in advance. |
