THE METHOD OF LINES SOLUTION OF THE DISCRETE ORDINATES METHOD FOR RADIATIVE HEAT TRANSFER IN ENCLOSURES CONTAINING SCATTERING MEDIA

A radiation code based on the method of lines (MOL) solution of the discrete ordinates method (DOM) for three-dimensional radiative heat transfer in rectangular enclosures containing gray, absorbing, emitting, isotropically and anisotropically scattering media was developed. Predictive accuracy of the code was evaluated by applying the code to 1-D and 3-,D problems containing scattering media and benchmarking its predictions against exact solutions, the zone method, and Monte Carlo solutions. Favorable comparisons reveal that MOL solution of the DOM provides accurate solutions for modeling radiative heat transfer in 3-D rectangular enclosures containing purely scattering or absorbing, emitting, and scattering media with isotropic or anisotropic scattering properties.
