Detailed Description

This boundary condition provides a turbulence dissipation wall constraint for low- and high-Reynolds number turbulence models.

The condition can be applied to wall boundaries for which it

  • calculates epsilon and G
  • specifies the near-wall epsilon value

where

$ epsilon $ = turbulence dissipation field
$ G $ = turbulence generation field

The model switches between laminar and turbulent functions based on the laminar-to-turbulent y+ value derived from the kappa and E specified in the corresponding nutWallFunction.

Usage
Example of the boundary condition specification: 
<patchName>
{
    type            epsilonWallFunction;
}
