摘要

This paper describes the numerical calculation of radiant heat exchange within thermal enclosures using four different radiation models: Monte Carlo-, Discrete Transfer-, Discrete Ordinates- and Boundary Element- Method. A comparison of the incident heat flux and heat source predicted by the four models is reported for two test cases representing combustion chambers. Conclusions are drawn concerning accuracy of the numerical methods, sensitivity of angular discretisation, spatial discretisation and computational performance. It is shown that the predictions of all the methods are in close agreement, within an error margin generally below 5%.
