Heat loss study of trapezoidal cavity absorbers for linear solar concentrating collector

Performance evaluation of a direct vapor generation supercritical ORC system driven by linear Fresnel reflector solar concentrator

“…Singh PL et al [15,16] analyzed a LFR with trapezoidal cavity receiver, which bundles multiple tubes as absorber. It showed that the thermal efficiency of the solar receiver with round pipe absorber is higher (up to 8%) than rectangular one.…”

Line-focusing concentrating solar collector-based power plants: a review

“…In addition, blocking occurs when the reflected rays from the reflectors are blocked by the other reflector rows and thus prevented from reaching the receiver of LFR system (Sharma et al 2015b). Several authors have proposed a LFR design with a constant width of the reflectors/mirrors and shifting of mirrors such that there is no blocking at noon (Mathur et al 1991a, b;Singh et al 1999Singh et al , 2010. The analysis has been done for different receiver shapes, like, tubular, triangular, horizontally flat, vertically flat, etc.…”

Analysis of entropy production vs . energy efficiencies during natural convection in porous trapezoidal cavities exposed to various thermal ambience

“…Natural * Corresponding author. convective heat transfer in the trapezoidal enclosures (both fluid and porous media) are highly useful for the applications in the greenhouse-type solar stills [34] , desalination [35] , solar collectors [36][37][38][39] , solar cavity receiver [40] , solar distiller [41] , solidification of phase change materials [42] , molten metal processing [43] solar cooking [44] , designs of building and attics [45] , heat recovery or indirect heat exchangers [46] etc.…”
