totalFlowRateAdvectiveDiffusive

Description

The totalFlowRateAdvectiveDiffusive is a boundary condition that provides an inlet for species. The diffusion and advection fluxes are considered to calculate the inlet value for the species.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            totalFlowRateAdvectiveDiffusive;

    // Optional entries
    phi             <word>;
    rho             <word>;
    massFluxFraction <scalar>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: totalFlowRateAdvectiveDiffusive	word	yes	-
phi	Name of flux field	word	no	phi
rho	Name of density field	word	no	rho
massFluxFraction	Mass flux fraction	scalar	no	1.0

The inherited entries are elaborated in:

• mixedFvPatchField.H

• The massFluxFraction sets the fraction of the flux of each particular species.
