MONTE-CARLO SIMULATION OF RADIATIVE HEAT-TRANSFER IN ARRAYS OF FIXED DISCRETE SURFACES USING CELL-TO-CELL PHOTON TRANSPORT

An accurate simulation of radiative heat transfer in arrays of fixed d iscrete surfaces is challenging because of the complicated geometries that can shade and block many surfaces. This paper presents an innovat ive Monte Carlo scheme using cell-to-cell photon transport developed t o simulate monochromatic radiation impinging on an array of fixed disc rete elements. Results of the study show that cell-to-cell photon tran sport is an efficient method of simulating radiation heat transfer in complicated geometries. Sample calculations demonstrate the dependence of radiation heat transfer in the array on the geometry of the array elements. Copyright (C) 1996 Elsevier Science Ltd.
