The paper presents a design and operation analysis of an Integrated Collector Storage (ICS) solar water heater, which consists asymmetric Compound Parabolic Concentrating (CPC) reflector trough, while the tank comprises two concentric cylinders. annulus between these vessels is partially depressurized contains small amount in bottom outer vessel dominantly contributes to heat transfer from inne...

The objective of this paper is to investigate the theoretical performance Parabolic Trough Collector (PTC) using various nanofluids. performances are calculated for Al2O3, graphite, magnetite, SWCNH, CuO, SiO2, MWCNT, TiO2, Fe2O3, and ZnO in water heat transfer equations, thermodynamic properties nanofluid pumping power utilised development novel thermal model. efficiency PTC calculated, econom...

In the present work, a prototype of a new type of solar collectors, which called Direct Absorption Solar Collector, was built and its thermal performance is experimentally compared with conventional flat plate solar collector under transient and steady state conditions. Different volume fractions of multi wall carbon nanotubes in water and ethylene glycol mixture (70%:30% in volume) were used a...

Solar co-generation, i.e., the generation of electricity and heat in a single device by concentrating sunbeams, has potential to significantly increase overall system performance. The main challenge is related cooling solar cells. In order do so, it essential reduce thermal resistance between cell transfer fluid. This paper features optimization procedure low-cost custom concentrated photovolta...

A mathematical model for computing the thermal performance of an air heater with a truncated compound parabolic concentrator having a flat one-sided absorber is presented. A computer code that employs an iterative solution procedure is constructed to solve the governing energy equations and to estimate the performance parameters of the collector. The effects of the air mass flow rate, the wind ...

Solar parabolic concentrating collectors are widely and efficiently used in electrical generation. They were experimentally validated in worldwide pioneer plants. SEGS-VI 30 MW solar power plant built in southern California is one of these plants that was commissioned many years ago. In this work a possibility of installing such plant in Makkah, 21.4 °N located in moderate latitudes is studied....
