Simulation of the water outlet temperature in a solar Parabolic Trough Collector in the Errachidia site

The study of the water heating by parabolic trough collector (PTC) includes two essential parts. The first part treats the numerical simulation of the direct normal irradiation in absorber tube. The second part is entirely reserved to study the heat exchange of the absorbent tube to determine the outlet temperature of the fluid (water). The main objective of this work is to simulate the outlet temperature of the circulating fluid in the absorber tube of the sensor with concentration effect. For this, a mathematical model is established to control the fluid outlet temperature. After a theoretical study, we established the water outlet temperature by a simulation the thermal performance of PTC under climatic conditions of Errachidia region (Southern Morocco) using Matlab Simulink and Trnsys software in typical days of year.
