Abstract

Improvements of the Monte Carlo method for radiative heat transfer Z.

Numerous investigations were made, where this method was applied. A weak convergence of the temperature-iterative procedure and necessity to follow multiple reflection, especially at a high reflectivity of the walls, cause the classic Monte Carlo method to be very time- and work-consuming. The inconveniences of the classic Monte Carlo method encouraging its improvement are: incorporation of the Exodus-method to spectral analysis of the thermal radiation and the application of dimensionless irradiation ratios to the modelling of radiative heat fluxes. 1 Modelling of radiative heat flux The rad
