Field Function Reference

The following primitive field functions are made available to the simulation when the K-Epsilon turbulence model is used. These objects all have the same base properties.

 Turbulent Kinetic Energy

The transported variable .

   

 Turbulent Dissipation Rate

The transported variable .

   

 Turbulent Viscosity

The turbulent viscosity .

   

 Effective Viscosity

The sum of the laminar and turbulent viscosities, .

   

 Turbulent Viscosity Ratio

The ratio of turbulent to laminar viscosity, .

   

 Wall Y+

The value where is the reference velocity computed according to the selected wall treatment, is the normal distance from the centroid to the wall in wall-adjacent cells and is the kinematic viscosity.
