Detailed Description

template<class laminarThermophysicalTransportModel>
class Foam::laminarThermophysicalTransportModels::FickianFourier< laminarThermophysicalTransportModel >

Multi-component Fickian and Fourier based temperature gradient heat flux models with optional Soret thermal diffusion of species for laminar flow.

The mixture 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

laminar
{
    model           FickianFourier;

    mixtureDiffusionCoefficients yes;

    Dm // [m^2/s]
    {
        O2 1e-2;
        O3 5e-2;
        N2 1e-2;
    }

    DT // [kg/m/s] Optional
    {
        O2 1e-2;
        O3 5e-2;
        N2 1e-2;
    }
}

or if binary mass diffusion coefficient functions are available they can be mixed to form the mass diffusion coefficients w.r.t. the mixture:

laminar
{
    model           FickianFourier;

    mixtureDiffusionCoefficients no;

    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;
    }
}
