Abstract

In this work, the optical analysis of a piece-wise concentrator ( PWC), of the low concentration class, is presented. This concentrator, can be easily fabricated from known unequal length mirror segments, arranged in a certain order to form its reflecting surface, which is capable of producing a predetermined flux distribution over a flat receiver surface. The construction equations of the transverse shape of the reflecting surface, which produce a uniformly illuminated portion on a flat receiver around the Noon time, are derived from the optical geometry principles. Also, the hourly flux distribution over the receiver surface is numerically predicted by the ray tracing technique, with an especially made computer program. The theoretical results are compared with the experimental data collected from outdoor tests on a prototype concentrator, which a maximum concentration ratio of 3.64, designed and built for this purpose. The flux distribution is measured in terms of the currents (from a small battery) through some photo to resistance located at different points on the receiver surface. The local concentration ratio at these points is calculated as the local flux divided by that measured by another photo resistance directed towards the sun. The experimental data are given in graphical form.
