Simulation de l’écoulement turbulent et du transfert de chaleur dans un convertisseur thermo-solaire à air comportant de chicanes triangulaires orientées en amont et en aval.

Abstract

One key problem of using solar energy is low heat exchange with the air directed into the vein of the solar dynamic. For against the introduction of baffle (obstacles) arranged in rows in the ducts of these systems greatly improves heat transfer. In this work, we added roughness level of insulation to increase the exchange surface and consequently give a fluid particle trajectory very important to capture the maximum energy. We made a numerical study using the calculation code "Fluent" to study the dynamic and thermal behavior of the airflow in these planar solar collectors (solar plane with triangular roughness in tow type of direction .
