Detailed Description

Mixed boundary condition for temperature, to be used in the flow and pyrolysis regions when a film region model is used.

Example usage:

myInterfacePatchName
{
    type            filmPyrolysisRadiativeCoupledMixed;
    Tnbr            T;
    kappaMethod     fluidThermo;
    kappa           none;
    qr              qr;
    filmDeltaDry    0.0;
    filmDeltaWet    3e-4;
    value           $internalField;
}

Needs to be on underlying mapped(Wall)FvPatch. It calculates local field as:

    ratio = (filmDelta - filmDeltaDry)/(filmDeltaWet - filmDeltaDry)

when ratio = 1 is considered wet and the film temperature is fixed at the wall. If ratio = 0 (dry) it emulates the normal radiative solid BC.

In between ratio 0 and 1 the gradient and value contributions are weighted using the ratio field in the following way:

    qConv = ratio*htcwfilm*(Tfilm - *this);
    qRad = (1.0 - ratio)*qr;

Then the solid can gain or loose energy through radiation or conduction towards the film.

Notes:

• kappaMethod and kappa are inherited from temperatureCoupledBase.
• qr is the radiative flux defined in the radiation model.
