Detailed Description

Radiation boundary model for opaque reflective walls. It requires to specify a wallAbsorptionEmissionModel and the reflected fraction in boundaryRadiationProperties file fd is the diffusive reflected fraction. 0 all the incoming flux is specularly reflected and 1 all is diffusive reflected. fd is used in the calculation of the specular reflection (rSpec) and the diffusive reflection (rDiff). Absorptivity and emissivity are independent of fd.

Usage

    type        opaqueReflective;

    fd          0.0;

    wallAbsorptionEmissionModel
    {
        type            multiBandAbsorption;
        absorptivity    (0.3 0.7);
        emissivity      (0.3 0.7);
    };
