Each turbulence model can be applied successfully to some turbulent flows but not satisfactorily to others. This paper analyzes different modeling assumptions and various proposed turbulence models. Prediction of free shear flows, wall shear flows, unsteady flows, and complex three-dimensional flows are also given to show the capabilities and limitations of the existing turbulence models.
