Detailed Description

template<class BasicThermophysicalTransportModel>
class Foam::MaxwellStefan< BasicThermophysicalTransportModel >

Base class for multi-component Maxwell Stefan generalised Fick's law diffusion coefficients based temperature gradient heat flux model with optional Soret thermal diffusion of species.

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.
