Class
    Foam::porousModels::VollerPrakash
 
Description
    Porous model to apply a porous media on a solid phase.
 
    Based on the references:
    -# V.R. Voller and C. Prakash, A fixed grid numerical modelling
       methodology for convection-diffusion mushy phase-change problems,
       Int. J. Heat Mass Transfer 30(8):17091719, 1987.

Usage
    Example usage:
    \verbatim
    interfacePorous
    (
        (solid and liquid)
        {
            type            VollerPrakash;
            solidPhase      alpha.solid;
            Cu              1e7;
        }
    );
    \endverbatim
 
    Where:
 
    \table
        Property    | Description           | Required    | Default value
        solidPhase  | Solid phase name      | yes
        Cu          | Model constant        | yes
    \endtable
