Abstract
The implementation of the Monte Carlo (MC) method for the radiative transfer in a one-dimensional medium slab is reported and validated through comparisons with an in-house, discrete ordinates method (DOM)-based code, as part of an ongoing research on the application of MC methods in radiative transfer problems. The method is implemented as a Fortran code and is capable for solving the radiative transfer problem for homogeneous and non-homogeneous media subjected to isothermal or non-isothermal conditions and bounded by black or gray walls. Three widely used spectral models are coupled to the MC solver: the gray gas (GG), the weighted-sum-of-gray gases (WSGG), and the spectral line-based WSGG models (SLW). The comparisons with the DOM solution are carried out for a set of test cases, and show a remarkable agreement for the two solutions regardless of the spectral model employed, attesting that the MC method was implemented successfully
