Hi guys,
Could anyone please tell me how to actually predict transition in a 3D CFD simulation, especially at the geometry wall? I'm using the SST Gamma Theta transition model to conduct my simulations, where I have the parameters of turbulent kinetic energy, intermittency and ReTheta of the flow are made available. I'm not sure if they will exist at the geometry wall due to the no slip condition. I would like to separate the region of the laminar flow and turbulent flow, i.e. some flow variable that represent only transition or laminar or turbulent. Have seen of the use of wall shear stress (contour) to predict transition, but is there a way to draw a definite line of the flow transition? Any help is greatly appreciated Thanks in advance
