Class
    Foam::laminarThermophysicalTransportModels::MaxwellStefanFourier
 
Description
    Multi-component Maxwell Stefan generalised Fick's law diffusion coefficients
    and Fourier based temperature gradient heat flux model with optional Soret
    thermal diffusion of species for laminar flow.
 
    The binary mass diffusion coefficients are specified as Function2<scalar>s
    of pressure and temperature but independent of composition.
 
    The heat flux source is implemented as an implicit energy correction to the
    temperature gradient based flux source.  At convergence the energy
    correction is 0.
 
Usage
    \verbatim
    laminar
    {
        model           MaxwellStefanFourier;
 
        D // [m^2/s]
        {
            O2-O2 1e-2;
            O3-O3 5e-2;
            N2-N2 1e-2;
            O3-O2 5e-2;
            O3-N2 5e-2;
            O2-N2 1e-2;
        }
 
        DT // [kg/m/s] Optional
        {
            O2 1e-2;
            O3 5e-2;
            N2 1e-2;
        }
    }
