[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? #kOmega #fluidmechanics101 #cfd ==================================================== Some useful references: 1) NASA Turbulence Modelling Resource - The Wilcox k Omega Model 2) J.
