Abstract

A numerical analysis method has been presented for predicting radiative heat transfer between three-dimensional isothermal black bodies of arbitrary shapes. The body is composed of numerous arbitrary polygons, which can be generated by CAD or CAM, and an effective exchange area of the three-dimensional body is introduced for the numerical analysis. The present numerical solutions of simple body shapes show good accordance with the the existing analytical solutions. Radiative exchange between two arbitrary bodies can be calculated by using the effective exchange areas. The effective exchange area of an automobile crank shaft model composed of 181 polygons was demonstrated as a calculation example. The numerical solutions converge for a rather small number of projections.
