Parameters - Turbulence Parameters:

This form allows the analyst to specify the type of turbulence model to be used.

Available models include Zero Equation Model, and  Standard K-Epsilon model.

Zero Equation Model requires the least amount of computational resources, although it is the least accurate. Claims have been made that for many electronics cooling applications, zero equation model may suffice. This model requires a characteristic length and characteristic velocity.
K-Epsilon model requires input of several parameters. The standard values for these parameters found in literature are default values shown in the data boxes. It is recommended that these values be changed only by those experienced in turbulence modeling techniques.
