Parabolic trough solar collectors (PTSCs) are commonly used for applications that reach a temperature of up to 500 °C. Recently, improving the efficiency PTSCs has been focus research because have advantages, such as cost and size reduction improved optical thermal performance. This study summarizes relevant published on preparation, properties experimental behavior PTSCs. Analyzing modeling me...

Abstract In recent decades, solar energy has emerged as the most promising renewable source and best alternative to conventional due its abundant availability, free, clean, no atmospheric hazards, eco-friendly, sustainable nature, other factors. Because of wide temperature range (up 400 °C), parabolic trough collector is commonly used in concentrated power technology. A can be divided into two ...

Energy is one of the essential requirements of livinghood. In present scenario conventional energy resources for producing energy to sustain our lives has become a necessity. Since these sources are depleting at faster rate and cost of energy is increasing simultaneously, so conversion of renewable form of energy is much desired and solar energy is a good resource. The present work is based on ...

The objective of this work is to study the thermal behavior a solar heating system using an active layer, integrated in wall and supplied with hot water by parabolic trough collector (PTC). prototype includes PTC surface area 1.8m 2 , tank layer wall. A complete simulation model TRNSYS 16 software has been established. Simulation tests under climatic conditions city Errachidia located southeast...

The organic Rankine cycle (ORC) is an effective technology for power generation from temperatures of up to 400 °C and capacities 10 MWel. use solar irradiation driving ORC a promising renewable energy-based due the high compatibility between operating thermal collector technologies temperature needs cycle. objective this review paper present discuss operation principles solar-ORC wide range sys...

Literature about entropy generation analysis of a wavy enclosure is scare. In this paper. a FORTRAN cod using an explicit finite-volume method was provided for estimating the entropy production due to the natural convection heat transfer in a cosine wavy absorber solar collector. The volumetric entropy generation terms both the heat transfer term and the friction term were straightly calculated...

A new type of improved solar cooker based upon the use of a single vacuum tube is presented in this paper. The proposed cooker utilizes a solar collector consisting of parallel plane rectangular glass mirror strips mounted inside a wooden frame and requiring one dimensional solar tracking through a common driver. The proposed design can be either installed over the roof top of a house or near a...
