Abstract
A blocked-off region concept is implemented with the modified discrete ordinates method (MDOM) to solve combined conductive and radiative heat transport problems in irregular geometries. The media analyzed are absorbing, emitting and isotropically or anisotropically scattering. The walls have temperature or flux boundary conditions. The finite-volume method is used to solve the energy equation and the modified discrete ordinates method is employed to solve the radiative transfer equation. The SDOM and MDOM are compared in all cases, and the accuracy of the results is assessed by comparing the results with those obtained by other researchers. The results confirm the capability of the MDOM to minimize the anomalies due to ray effects in combined mode heat transfer problems.
