- Abstract
- Two radiative heat transfer codes, one based on the six-flux radiation model, and the other based on the S4 discrete ordinates model, have been developed. Both the radiation models approximate the angular variation of the radiation intensity by solving the radiation transport equation in a predetermined number of directions so that the angular integral is removed, resulting in differential equations which can be solved simultaneously with the differential equations of fluid flow, chemical reactions and heat transfer. The limited evaluation of these two models indicates that the six-flux model under-predicts the radiant heat fluxes by up to a factor of two, while the discrete ordinates model affords sufficiently accurate predictions for engineering heat transfer calculations.
