Effects of radiation characteristics on the calculation accuracy of Monte Carlo method in three-dimensional cylindrical radiation heat transfer problem

Abstract

This study investigates the impact of angular mesh dispersion, scattering albedo, and surface emissivity on the computational accuracy of the Monte Carlo method for solving the radiation heat transfer problem with participating medium in a three-dimensional cylindrical coordinate system under isothermal radiation equilibrium conditions. The relationship between the surface emissivity and the minimum number of beams is quantitatively analyzed by collating the data, and the maximum allowable optical thickness under a certain number of bundles is obtained.
