Abstract
  • In this work, a method for solving the differential form of the radiative transfer equation was implemented into an existing three-dimensional thermal-hydraulic computer program known as TEMPEST. The method used was the P-l approximation, where the angular distribution of the radiation intensity is represented by a truncated series of spherical harmonics. To determine the accuracy and limits of P-l formulation, a series of comparisons were made between TEMPEST results and existing solutions. Evaluations were made for problems involving thermal radiation only, radiation and conduction, and finally, radiation, conduction, and convection. In general, the P-l method yielded acceptable results for radiation problems with large optical thicknesses (τ₀ > 1.0) or combined radiation and conduction problems with participating media. The accuracy of results for radiation problems involving little or no optical thickness are highly dependent on the geometry of the problem.
