Radiative heat transfer analysis by the Radiative Heat Ray method (Analysis in a two-dimensional model)

Abstract

The authors developed a new calculation method for the analysis of radiative heat transfer. This new method uses READ (radiative energy absorption rate distribution). READ is very useful, especially when applied to the Monte Calro method, to solve the radiative heat transfer problem in furnaces, because the calculation using READ results in a significant reduction i computation time and improvement in accuracy. To calculate READ more accurately, a new method, which is called the "Radiative Heat Ray method", was also developed by the authors. This new method can calculate READ more accurately with less computing time compared with the Monte-Carlo method.
