The variables [kappa] and [sigma] represent the absorption and extinction coefficients of the medium, respectively, and [mu], [xi], and [eta] are the directional cosines that describe the direction of the radiant intensity.
The spectral radiative transfer equation (RTE) can be simplified by Discrete Transfer Radiation approach which is the commonly used radiation model for HVAC applications this is done by Using ray-tracing technique to integrate radiant intensity along each ray:
Integrating the radiant intensity I over the solid angle subtended by an element area on the floor and normal to the element area of the tube-reflector assembly will give the net radiant heat flux on the floor.
