Performance Simulation of Solar Trough Concentrators: Optical and Thermal Comparisons
نویسندگان
چکیده
The solar trough concentrator is used to increase the radiation intensity on absorbers for water heating, desalination, or power generation purposes. In this study, optical performances of four concentrators, viz. parabolic (PTC), compound (CPC), surface uniform (SUC), and trapezoid (TTC), are simulated using Monte Carlo Ray Tracing method. Mathematical models concentrators first established. distributions their receivers then simulated. heating finally compared. results show that, as a high-concentration ratio concentrator, PTC can achieve highest heat flux, but suffers from worst uniformity absorber, which only 0.32%. CPC generate flux among rest three low-concentration concentrators. Compared with CPC, TTC has better uniformity, its light-receiving 70%. SUC beneficial 87.38%. Thermal analysis that temperatures inside directly proportional wall temperature, temperature rise in smallest TTC. concentrators’ thermal deformations positively correlated temperatures. radial deformation much larger than those other equivalent stress found SUC, long-term operation system.

Natural convection heat transfer in V-trough solar concentrators
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 cylindrical cavity-receiver containing a tubular absorber that uses air as the heat transfer fluid is proposed for a novel solar trough concentrator design. A numerical heat transfer model is developed to determine the receiver’s absorption efficiency and pumping power requirement. The 2D steady-state energy conservation equation coupling radiation, convection and conduction heat transfer is ...
