使用kOmegaSST模型,感觉Omega算得不对
-
使用buoyantSimpleFoam求解器,使用kOmegaSST模型计算得到的k和omega如下所示。
感觉omega很奇怪,几乎均匀分布,只在壁面附近有变化,请问我算的omega合理吗?谢谢!

我的omega文件是:
dimensions [0 0 -1 0 0 0 0]; internalField uniform 300; boundaryField { inlet { //type calculated; //value uniform 0.12; type turbulentMixingLengthFrequencyInlet; mixingLength 0.002; value uniform 300; } outlet { type inletOutlet; inletValue uniform 300; value uniform 300; } smooth_wall { type omegaWallFunction; value uniform 300; } ribbed_wall { type omegaWallFunction; value uniform 300; } symmetry { type symmetryPlane; } }
