[CFD] The k - epsilon Turbulence Model

An introduction to the k - epsilon turbulence model that is used by all mainstream CFD codes (OpenFOAM, Fluent, CFX, Star, COMSOL, Saturne). The following topics are covered: 1) 9:30 What is the standard k - epsilon model? 2) 11:05 How has the model evolved over time and what variant am I using? 3) 13:30 What are the damping functions and why are they needed? 4) 17:56 What are high-Re and low-Re formulations of the k - epsilon model? #cfd ==================================================== Some useful references: 1) W.
