It is important to shorten the computation time of radiative heat transfer when doing a conjugate numerical heat transfer analysis. The relation between the computation time and the total number of surface elements is shown for an analysis of radiative heat transfer. A method that shorten the computation time by reducing element number has been developed. The method merges elements of low radiative heat flux using the results of a rough calculation. It seems promising for reducing the computation time without increasing errors. The distribution of radiative heat flux on a wafer in a lamp heating apparatus was calculated using the method. The results show that the distribution of the heat flux can be reduced by using a diffusive reflector.
