Design fabrication and heat transfer Analysis of cavity absorber for a Linear fresnel reflector solar Concentrator system

Abstract

The linear Fresnel reflector solar concentrator LFRSC system is a newlinesolar thermal energy system currently used for domestic and industrial newlineapplications The system uses parallel rows of mirrors lined up underneath a newlinelong elevated thermal absorber The mirrors move so as to focus solar newlineradiation onto the absorber The absorber contains a bank of water tubes newlinethrough which water is circulated It gradually absorbs heat energy by the newlineradiation reflected from mirrors This thesis mainly addresses a broad range of newlinedesign issues related to absorber of LFRSC system newlineThe performance of LFRSC system depends on the design newlineParameters mass flow rate desired temperature difference tracking accuracy newlineEtc In the present work an analytical simulation is done to select the system newlinedesign parameters using MATLAB program The selected value of each newlinedesign parameters is used to measure the performance of the LFRSC system newline newline
