epsilonWallFunction

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
