Numerical calculation of view factors for an axially symmetrical geometry
- Sumitomo Metal Industries, Ltd., Amagasaki (Japan). Advanced Technology Research Labs.
A new numerical method for calculating the view factors for an axially symmetrical geometry has been developed. The assumption is that each object can be approximated by a truncated hollow cone. The method consists of two parts. One is to determine the accepting region and the other the integration over that region. It is accurate and fast since the determination and the integration are analytical. It was compared with the area integration and Monte Carlo methods for concentric coaxial cylinders, and was seen to be 19 times and 3 times faster than them, respectively. It was applied to a CZ puller. The Czochralski (CZ) method, by which a round single crystal is pulled up from melt, is widely used in industry today for growing single crystals of Si.
