Use the same case and data files as you downloaded in the Laminar setup for the geometry and mesh.
Now, set up the k-ε model for turbulence. In Solution Setup-Models, double click the previous "Viscous-Laminar" option to open the dialogue. Select the "k-epsilon (2eqn)" model for turbulence. Leave the model constants the same as defined in the dialogue below; these values have been refined to constraints of the model and are typically not varied.
The following empirical formulas are useful in defining this model. I is the turbulent intensity, d is the hydraulic diameter, and d is the jet diameter.
