The Central Receiver Test Facility (CRTF), operated for the Department of Energy by Sandia National Laboratories in Albuquerque, New Mexico, was constructed to evaluate design concepts for solar central receivers. The facility consists of an array of 222 heliostats in a northfield configuration that reflects and focuses the sun's energy toward a tower 60 m high. Throughout the history of the CRTF, there has been an interest in beam redirectors or reconcentrators. The objective of this paper is to discuss the numerous code modifications required for the facility code HELIOS to be able to model the redirector-radome configuration. This model simulates the solar flux-density pattern from reflecting concentrators and follows the incident solar radiation through the atmosphere, the collection system, and finally onto the target. The model includes most pertinent factors that influence the optical performance of a collector system. Although the standard output contains information concerning sun shape distributions and atmospheric attenuation, probably the most useful output is the flux-density pattern at a grid of points on a receiver surface and the integral of this distribution over the surface to obtain power. 3 refs., 17 figs.
