Comparative optical analysis of cylindrical solar concentrators.
A comparison of the intensity distribution in the receiver plane for five different types of cylindrical concentrators is made. To this end, our previous 2-D optical analysis for nonperfect concentrators with plane receivers is used. Values of the local and mean concentration factors for a characteristic set of parameters of each concentrator are obtained and compared. The results show that the cylindrical-parabolic concentrator attains the highest concentration factors among the concentrators considered.
