Solar thermal collectors, such as flat plate and evacuated tube are used for maximum of 60–80 °C temperature parabolic trough collectors 700–900 ranges. It is needed to develop analyze solar compound (CPC) which can operate in an intermediate range from 50–300 industrial domestic applications. However, optical performance CPC strongly influenced by concentration ratio. The current study present...

Abstract In present paper, thermodynamic analysis and techno-economic assessment of an organic Rankine cycle (ORC) coupled with solar parabolic trough collector (PTC) are investigated. The economic models, based on the principles thermodynamics heat transfer, as well dynamic analysis, developed for components combined system. By performing a parametric study, effects outlet temperature (TPTC,ou...

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...

This thesis documents my personal contribution to the development of a hydraulic-based actuation system for a solar trough collector. The goal of this project was to design the actuation system using hydraulic actuators for a four meter solar collector prototype in Pittsfield, New Hampshire. After considering several hydraulic system architectures and conducting in-depth analysis into two of th...

Aiming at the large carbon emissions of facility agricultural heating in severe cold regions winter, a Compound Parabolic Concentrator based soil system was presented. The integrated with novel trough and used for agriculture. Following structure Concentrator, TracePro software selected to trace light Concentrator. And variation trend escape rate different incident angles analyzed. Based on cal...
