Comparisons of cylindrical and rectangular media radiative transfer solutions using the S-N discrete ordinates method
The application of the S-N discrete ordinates method is compared for r-z and x-y problems with similar boundary conditions. The complexities of the r-z solution come from the additional angular derivative, which makes this into a virtual three-dimensional problem. Effects of spatial differencing schemes, phase functions, and grid spacing are considered and compared for these x-y and r-z problems.

Radiative transfer solutions for cylindrical coordinates with emitting, absorbing, and anisotropic scattering medium
The radiative transfer equation is solved by the S-N discrete ordinates method in one-dimensional radial and two-dimensional r-z coordinates systems. The walls of the enclosures are diffuse, and the participating medium absorbs, emits and anisotropically scatters the radiative energy. Diffuse wall incidence, isothermal medium emission and collimated incidence problems are considered. Effects of the scattering phase functions on average incident radiation and net radiative heat fluxes are studied. In addition, the effects of scattering albedo, optical thickness and the wall emissivity are briefly discussed.
