A method has been developed for adjusting a TRASYS enclosure form factor matrix to unity. This approach is not limited to closed geometries, and in fact, it is primarily intended for use with open geometries. The purpose of this approach is to prevent optimistic form factors to space. In this method, nodal form factor sums are calculated within 0.0

Tsuyuki- Jet Propulsion Laboratory California Institute of Technology Pasadena, California 91109 SUMMARY A method has been This approach developed for adjusting is not limited to closed a TRASYS geometries, enclosure and in fact, form factor matrix it is primarily intended with open geometries. The purpose of this approach is to prevent optimistic space. In this method, nodal form factor sums are calculated within 0.05 TRASYS, although deviations as large employed to distribute the difference with method, a comparison this radiation conductors. Exterior eases, nodes predictions when compared be acceptable, the nodes. with cold the form These temperatures results computation analyzed determined. for the hot and cold while indicate error interior nodes that temperature is lumped into the to space.
