alphatFixedDmdtWallBoilingWallFunction

Description

The alphatFixedDmdtWallBoilingWallFunction is a boundary condition that provides a simple alphatPhaseChangeJayatillekeWallFunction condition with a fixed volumetric phase-change mass flux.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type         compressible::alphatFixedDmdtWallBoilingWallFunction;
    vaporPhase   <word>;

    // Optional entries
    relax        <scalar>;
    fixedDmdt    <scalar>;
    L            <scalar>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: compressible::alphatFixedDmdtWallBoilingWallFunction	word	yes	-
vaporPhase	Name of the vapor phase	word	yes	-
relax	Relaxation factor for dmdt	scalar	no	1.0
fixedDmdt	Volumetric phase-change mass flux in near wall cells	scalar	no	0.0
L	Latent heat	scalar	no	0.0
