(362c) Radiative Heat Transfer Modeling Using Monte Carlo Techniques and CFD for Industrial Furnaces

The hottel zone method is well-established technique for analyzing radiation transfer problems in fuel-fired furnaces. However, determining the directed flux areas of complex enclosures using this method is still challenging task. In this paper, a stochastic model based on Monte Carlo (MC) method has been developed to calculate direct and total exchange areas (DEAs and TEAs) for furnaces with complex geometries. Several CFD case studies were conducted to provide valuable insight into furnace design, although they are quite computational expensive and require a fast workstation. The results of hottel zone method and CFD studies are comparable and both in a good agreement with the industrial data.
