“…Since the proposal of VSC by Hollands [36] in 1971, many works have been reported focusing on analysis of its optical performance and the potential for energy collection in a particular location over a period with or without tracking [37][38][39][40][41][42][43][44][45]. Experimental works were also conducted to evaluate the optical performance of the VSCs.…”

“…In a parallel study Mannan and Bannerot (1978) extended the idea of a single facet reflector V-trough to a two-facet design, which they found offered a compromise between a V-trough and a compound parabolic concentrator (CPC). In subsequent studies Puri (1981) and Sorour et al (1991) also showed that the performance of V-trough receivers was dependent not only on the concentration ratio and acceptance angles but also on the length of the trough.…”

The use of V-trough concentrators offers a simple approach to increasing the radiation incident on a solar receiver; this is particularly useful for increasing the temperature in thermal systems.However in order to accurately predict the performance of thermal systems under concentrated radiation, there is a need to understand the heat loss from them. This study experimentally shows that, for a laterally and longitudinally inclined enclosed V-trough concentrator, the natural convection heat loss can be predicted using an equation of the form Nu = a Ra b for Rayleigh numbers between 2x10 3 and 1x10 8 . It is suggested that the relationship is a good representation of heat transfer in enclosed V-trough concentrators under most practical orientations, and thus lends itself for implementation into design models for V-trough concentrators.
