Summary

The paper describes an improved numerical method for analyzing radiative heat transfer that is accurate with complicated geometry and has reasonable computational time. The authors propose several methods that use fewer emitted rays for simulating radiative energy. The method of distributing emitting points by staggering allocated square patches shows the best performance, and it makes possible the calculation about twice as fast as the conventional method. The authors also considered applying the method to the numerical flow analysis by using a rough mesh generated from a mesh for fluid calculation. The example calculations for an air-conditioning system which uses thermal radiation panels were carried out.
