COMPUTATION OF RADIANT-HEAT TRANSFER ON A NONORTHOGONAL MESH USING THE FINITE-VOLUME METHOD

The finite-volume method has been shown to effectively Predict radiant exchange in geometrically simple enclosures where the medium is gray, absorbing, emitting, and scattering. Cartesian and circular cylindric al meshes have always been used. The present article shows that the me thod applies equally well to geometrically complex enclosures where no noythogonal, boundary-fitted meshes are used. This development permits radiant heat transfer to be computed on the same mesh employed to sol ve the equations of fluid motion.
