Detailed Description

This is a mass-fraction boundary condition for a semi-permeable baffle.

This condition models a baffle which is permeable to a some species and impermeable to others. It must be used in conjunction with a specieTransferVelocityFvPatchVectorField velocity condition, and a specieTransferTemperatureFvPatchScalarField temperature condition.

The mass flux of a species is calculated as a coefficient multiplied by the difference in a property across the baffle.

$\phi_{Yi} = c A (\psi_i - \psi_{i,n})$

where

$\phi_{Yi}$	=	Flux of the permeable specie [kg/s]
	=	Transfer coefficient [kg/m^2/s/<property-dimensions>]
	=	Patch face area [m^2]
$\psi_i$	=	Property on the patch [<property-dimensions>]
$\psi_{i,n}$	=	Property on the neighbour patch [<property-dimensions>]

A species that the baffle is permeable to will, therefore, have a coefficient greater than zero, whilst a species that does not transfer will have a coefficient equal to zero.

Usage

Property	Description	Req'd?	Default
`c`	Transfer coefficient	no	0
`property`	Property used to drive the transfer; massFraction, moleFraction, molarConcentration, or partialPressure	if c is non-zero
`phi`	Name of the flux field	no	phi
`U`	Name of the velocity field	no	U

Example of the boundary condition specification:

    <patchName>
    {
        type            semiPermeableBaffleMassFraction;
        property        molarConcentration;
        c               1e-3;
        value           $internalField;
    }
