Monte Carlo simulation of radiation heat transfer in a three-dimensional enclosure containing a circular cylinder
In any process involving high temperatures such as heat treatment, power generation, and other engineering applications, radiation heat transfer is an important mechanism. This paper presents the distribution of radiation heat flux within an enclosure containing a horizontal circular cylinder. Cases were examined both with and without an absorbing, emitting, and scattering medium present. The bottom surface of the square enclosure was considered a uniform heat flux surface, and the other surfaces were considered perfectly absorbing. A circular cylinder was located at various positions along the vertical centerline of the enclosure; its length was that of the enclosure depth. In the first part of this study (cases 1 and 2), different configurations were used with an optically thin ({tau} {much{underscore}lt} 1) medium in the enclosure, and in the second, different optical thicknesses were used with a fixed enclosure size. The amount of radiant energy transferred to the cylinder depends on its location, the optical thickness of the participating medium, and the enclosure depth. For the optically thin cases ({tau} {much{underscore}lt} 1) the Monte Carlo solution calculates geometric view factors.
