Turbulent Jet Setup and Solution

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. 

I = 0.16Re

d = d

l = 0.07d

ε = Ck/l

k = 1.5(UI)²
