Study on the radiative heat transfer by partition allocation method

In this paper, the radiative heat transfer in participating cylindrical medium is approximated by the Monte-Carlo method, in which the boundary flux distribution is calculated by the partition allocation method. Two temperature distribution of the absorbing-emitting-anisotropically scattering medium is selected: temperature varying along the axis direction (1 dimensional); temperature varying along the axis and radius direction simultaneously (2 dimensional). In the partition method, every sub-domain is isolated by imaginary equivalent black wall resulted from the incident radiative flux on the imaginary interface and overlaps each other. By the study on the 1D and 2D temperature distribution medium, the results indicate that the present partitioned treatment can save memory efficiently. The results also show that the temperature level in every domain, the overlap optical thickness and the aspect ratio may be three main parameters to influence the accuracy of partition allocation method.
