Abstract
This article presents results obtained with the even parity form of the radiative
heat transfer equation and the discrete ordinates method associated with the
Galerkin finite elements (EP-FE-DOM). The coupled conductive and radiative
heat transfer is considered in any bidimensional absorbing, emitting and
isotropically scattering media, enclosed by gray walls. All conventional flux
methods suffer from the difficulty in application to geometries that stray from
rectangular or cylindrical. The discrete-ordinates associated with finite elements
correct this defect easily, due to the natural implementation of unstructured grids
in the method. However, though this method can fit any kind of domain, as far as
we know, no applications and evaluations have been
