Concentrating sunlight with an immobile primary mirror and immobile receiver: Ray-tracing results

Using a combination of custom computer code and commercially available ray-tracing software, we explore variations of concentrator geometries where sunlight is first incident onto a stationary primary mirror of circular cross section. The reflected radiation is incident onto a smaller, secondary moveable mirror, which focuses the radiation onto a stationary target. Simulations for this trough geometry show peak concentrations of 38 solar equivalents. 2011 Elsevier Ltd. All rights reserved.
