Thermal Performance on Parabolic Solar trough Collector by using Rgo/Water Nanofluid

Abstract

The solar water heating systems are one of the popular devices to harness the sun radiation incident on the surface of earth at free of cost. The ASHARE standards 93-86 were followed to study the thermal performance of parabolic solar trough collector using rGO/water nanofluid with the mass fraction of 1% used as a working coolant. To enhance the efficiency regarding temperatures variations, flow rate, and incident solar radiations was examined. These results show that influencing of nanofluid on the collector had more efficient than with pure water owing to solar radiation and flow rate. The efficiency of solar parabolic trough collector has improved with an effect of nanofluid compared to pure water.
