Abstract
The laminar flow of ZrO2-water nanomaterial through the cooling duct of photovoltaic unit has been analyzed in this article. Two shapes for the ducts (circular and rectangular) were considered. The system with a rectangular duct has been equipped with confined jets with two arrangements. The finite volume method has been utilized for the simulation of the present three-dimensional models and a good agreement has been obtained. The uniformity of isotherms over the silicon layer has been improved by utilizing the new cooling system which leads to a longer lifetime. For the circular tube case, an increase in inlet velocity (V in) makes electrical () and thermal () performances enhance about 1.07% and 1.64%, respectively. With the increase in inlet temperature (T in) in both regions, and reduced by about 3.97% and 28.39%. Incorporating the rectangular duct and jets with proper design leads to increments of and about 58.91% and 3.84% when Ti n = 308.15 K, V in = 0.06 m/s.
