Class
    Foam::fv::oneResistanceHeatTransfer
 
Description
    Model for heat transfer between two phases. One heat transfer coefficient
    is used to calculate the heat flux from the temperature difference between
    two phases.
 
Usage
    Example usage:
    \verbatim
    heatTransfer
    {
        type            oneResistanceHeatTransfer;
        libs            ("libmultiphaseEulerFvModels.so");
 
        blending
        {
            type            linear;
            minPartlyContinuousAlpha.air 0;
            minFullyContinuousAlpha.air 1;
            minPartlyContinuousAlpha.water 0;
            minFullyContinuousAlpha.water 1;
        }
 
        air_dispersedIn_water
        {
            type            RanzMarshall;
            residualAlpha   1e-4;
        }
        water_dispersedIn_air
        {
            type            RanzMarshall;
            residualAlpha   1e-4;
        }
    }
    \endverbatim
