[CFD] The k-omega Turbulence Model 

An introduction to the k - omega turbulence model that is used by all mainstream CFD codes (OpenFOAM, Fluent, CFX, Star CCM+, COMSOL, Saturne). The following topics are covered:
1) 5:10 When was the k-omega model developed?
2) 12:28 What is omega?
3) 15:20 Why is k-omega better for aerodynamics than k-epsilon?
4) 16:43 What is the freestream dependency of the k-omega model?
