Numeric computation of the radiative heat transfer for vertical crystal growth of CdZnTe single-crystals

Abstract

A method for the computation of radiative heat transfer was suggested. It is based on numeric computation of heat flows from the muffle walls with a specified temperature to the ampoule walls with a temperature that needs to be estimated. The computation was realized in two steps. At the first step the form of view factors was determined with the use of analytic formulas. At the second step the heat flows were computed in the array of points on the ampoule and rod walls. Computations carried out for the CdZnTe system with the use of our algorithm
