Theoretical Study of the Compound Parabolic Trough Solar Collector

Abstract

Theoretical design of compound parabolic trough solar collector (CPC) without tracking is presented in this work. The thermal efficiency is obtained by using FORTRAN 90 program. The thermal efficiency is between (60-67)% at mass flow rate between (0.02-0.03) kg/s at concentration ratio of (3.8) without need to tracking system. The total and diffused radiation is calculated for Tikrit city by using theoretical equations. Good agreement between present work and the previous work.
