Low Reynold's k-epsilon model for Comsol v3.5

Laith Hurmez, University of Auckland

This implemented Low-Re k-epsilon Comsol model is based on the Launder-Sharma damping functions as described in Wilcox's Turbulence modeling for CFD book. Model implementation was in 2D under steady state situation but it can be extended to 3D with relative ease.

The variables solved in the model are U,V,P,k, and epsilt (epsilon tilde) using equation based modelling in general form.

The model also includes a k-e model from the chemical engineering module for comparison.

Hints: go to options-> expressions -> scaler or subdomain expressions to learn more about its implementation.
