In the present study, effect of receiver position error on optical and thermal performance a parabolic trough collector (PTC) has been studied. Optical analysis PTC carried out by using Monte Carlo ray tracing (MCRT) method. The solar heat flux profile obtained from is coupled with finite volume method (FVM) to study PTC. Simulations have done for experimental SEGS LS2 used in Sandia National L...

This paper evaluates a novel receiver design concept that implements photovoltaic (PV) cells on heat shields and bellows shields to capture optical spillage from central receiver and parabolic trough concentrating solar power (CSP) plants, generating electricity from concentrated light that would otherwise be wasted. A combination of conventional silicon and multi-junction concentrating PV (CPV...

In this article, the thermal performance of a parabolic trough solar air heater (PTSAH) with U-shaped heat exchanger is evaluated. The heater's examined by using copper and aluminum exchangers (UHX) without fin alternately, inside absorber tube placed at focal length nickel-coated stainless steel trough. system in form temperature difference achieved outlet for both efficiency. It observed that...

Abstract The mathematical modeling of hybrid nanofluid flow and heat transfer with entropy generation toward parabolic trough surface collector (PTSC) inside the solar-powered ship (SPS) is performed. model used non-Newtonian Oldroyd-B amidst a constant inclined magnetic field influence being considered. then reduced by adopting appropriate similarity transformation into higher-order nonlinear ...

Hydrogen has received increased attention in the last decades as a green energy carrier and promising future fuel. The integration of hydrogen, well development cogeneration plants, makes sector more eco-friendly, sustainable. aim this paper is investigation solar-fed system that can produce power compressed hydrogen. examined unit contains parabolic trough collector solar field, thermal storag...

in this paper, the performance evaluation of a two-way hybrid photovoltaic/thermal (pv/t) solar collector was analytically and experimentally carried out. mathematical expressions for operating parameters in glass to glass and glass to tedlar pv/t solar collectors were developed and experimentally validated by a glass to tedlar pv/t solar collector system. also the influence of air flow rate on...
