Class
    Foam::adsorptionMassFractionFvPatchScalarField
 
Description
    This is a mass-fraction boundary condition for an adsorbing wall.
 
    This condition models a baffle which adsorbs some species and not 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
    concentration adjacent to the patch.
        \f[
            \phi_{Yi} = c A \psi_i
        \f]
        where
        \vartable
            \phi_{Yi}  | Flux of the adsorbing specie [kg/s]
            c          | Transfer coefficient [kg/m^2/s/<property-dimensions>]
            A          | Patch face area [m^2]
            C_i        | Property adjacent to the patch [<property-dimensions>]
        \endvartable
 
    A species that is adsorbed by the patch will, therefore, have a coefficient
    greater than zero, whilst a species that is not adsorbed will have a
    coefficient equal to zero.
 
Usage
    \table
        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
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            adsorptionMassFraction;
        property        molarConcentration;
        c               1e-3;
        value           $internalField;
    }
    \endverbatim
