Effet des paramètres opérationnels sur les performances d'un capteur solaire plan.

Abstract

The sun gives to the earth gigantic quantities of energy that can be used under different forms. In this work, we have studied the way to exploit the solar energy by thermal voice by using a flat plat collector. Before designing this device, it is important to study the effect of internal and external parameters on the working characteristics of the flat plat collector on permanent and transient regimes. For this, we have developed a calculating program in the laboratory. The resolution of the system of equations governing the thermal behavior of the flat plat collector has been done by using two numerical methods, Gauss-Seidel method and Runge Kutta 4 method. The results obtained have been valided by an experimental work in the same metheorogical data in the center of development of renewable energies. The results obtained allow us to precise the effect of internal and external parameters on the efficiency of the flat plat collector, and to show the important effect of the incident solar radiation.
