Abstract
The zonal-iterative calculation method for radiation heat transfer is developed for arbitrary number of zones (opaque diffusely-radiating and reflecting surfaces). This method is based on transformation of the initial integral equations to equivalent system of integral equations with smaller kernel norm. The method provides high accuracy at a small number of the zones. The method was used for analysis of effective radiation in an isothermal tube cavity with a longitudinal pyrometric slit. In this case one zone was enough and one of the particular solutions can be obtained analytically.
