Краткое описание

An OpenMP based fully parallel coupled Monte Carlo - Finite Volume method has been developed for solving coupled conduction-radiation in a three-dimensional cubical enclosure containing a semi-transparent grey gas. The divergence of radiative flux is determined using Monte Carlo method, while the energy equation is solved by the finite volume method. The Monte Carlo is a statistical method which simulates radiation heat transfer by tracking the histories of a number of rays that represent energy bundles or photons traveling through the medium. The performance of the proposed method is evaluated for pure radiation problem prior to simulation of coupled conduction-radiation problem. A number of coupled conduction–radiation problems are considered and the results are compared with other benchmark approximate solutions. Numerical results on a multicore CPU showed that the proposed OpenMP implementation achieves good overall performance compared to the serial code and also the coupling of Monte Carlo with finite volume is stable and shows excellent agreement with the literature results.
