Efficiency Enhancement of a Solar Collector by using ZnO Nanofluid

Author : Firas Aziz Ali 1 Hareth Maher Abd 2

Date of Publication :13th September 2021

Abstract: The increasing demand to the energy nowadays has led investigators to give attention on solar energy. In this research, the performance of a flat solar collector has been studied experimentally. It was used water and ZnO/water nanofluid as working fluid with three values of mass fractions (0.01, 0.03, 0.06%) and (0.2, 0.5, 0.8 liter per minute) flow rate. The experimental study was performed at Mosul city/Iraq, during April and May in 2020. It was showed that the outlet temperature of the fluid, heat gain, experimental efficiency, thermal losses of the solar collector were increased as increasing of the solar intensity but decreased as the volumetric flow rate increased. The using of 0.06% of ZnO/water nanofluid increase the solar collector efficiency by 12% at the maximum value of volumetric flow rate
