Abstract

Based on a new formulation for radiative view factor from a sphere to a class of axisymmetric bodies, closed-form expression are developed for the radiation view factors from a phere to the external surface of a coaxil cylinder and from a sphere to an intersecting coaxil disk. The numerical results of the view factors are presented graphically in a wide range of parameters. At a limiting condition, one of the present formulas leads to the view factor from an annular ring to a coaxil hemisphere. The results are compared with those obtained earlier based on the Monte Carlo technique.
