Design Parameters Optimization and Theoretical Performance Analysis of Linear Fresnel Reflector Solar Concentrator with Multi Tube Absorber

Abstract

Linear Fresnel reflector solar concentrator technology is similar to solar trough technology in which the sunlight is reflected by a series of mirrors onto an absorber tube, thus linear F resnel reflector solar concentrator , is a linear line concentrator. The performance of the system depends on the design parameters, mass flow rate, etc. In the present work, by using MATLAB simulation program, a detailed design parameters analysis including the effect of variation in the height of the absorber, width of the absorber plane and the width of the reflector mirror elements on the concentration on the surface of the absorber plane has been made. The width of the absorber plane was investigated by using analytical and ray tracing technique s . Then, the optimized width of the absorber plane was used to design the absorber tubes. Also, detailed thermal performance analysis for the above design has been made. Results have been plotted graphically and discussed.
