Description

The epsilonWallFunction is boundary condition that provides wall functions for the turbulent kinetic energy dissipation rate (i.e. epsilon) and the turbulent kinetic energy production contribution (i.e. G) for low- and high-Reynolds number simulations.

Usage

The condition requires entries in both the boundary and field files.

Boundary file 

<patchName>
{
    type            wall;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type            epsilonWallFunction;

    // Optional entries
    lowReCorrection  <bool>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
type Type name: epsilonWallFunction word yes -
lowReCorrection Flag: apply low-Re correction bool no false

The inherited entries are elaborated in:

  • wallFunctionCoefficients.H
  • wallFunctionBlenders.H
