Abstract: Often in the course of analyzing complex engineering problems, it becomes necessary to adapt existing methods to alternate purposes. Analogies can be drawn between different physical phenomena which make it possible to analyze seemingly unrelated concepts such as fluid flow, heat transfer, diffusion phenomena, and electrostatic field theory using the same mathematical techniques. This paper presents how an analogy can be drawn between the determination of line-of-sight shape factors for analyzing radiation heat transfer between several bodies, and photon transport phenomena in radiation shielding analysis. An application of an existing method of determining the interaction of photon emitting radiation sources using three-dimensional combinatorial geometry techniques is used to calculate radiation shape factors for multiple bodies. A micro-computer based code was written to quickly and accurately compute these shape factors for generalized three-dimensional geometries. A graphical interface was developed to provide for a common geometry between the shape factor code and the finite element heat transfer code, and to enhance the input and output capabilities.
