Turbulence flow field can be predicted by directly solving the NS equations. However, this approach requires an extremely fine grid system and a very small time step to capture all the scales of fluid motions in the turbulent flow field. Obviously, this approach is too expensive for engineering application. In order to simulate the turbulence flow field with practical computational efforts, turbulence models were developed. Loosely speaking, current turbulence models can be categorized into two

UCLA has a korean prof. Kim which is the editor of Jounal of Fluid Physics, big Niu on the website of ucla, seach CFD or turbulence. Also there is one Chinese prof. And in mathematics dept, one Chinese big niu too
