摘要：

In the present work the effect of CeO2/water nanofluid on the performance of a flat plate solar collector was investigated experimentally. Two units of flat plate solar water heating systems, one for conventional mode and another for heat exchanger mode, with 100 liters per day capacity were fabricated with the collector area of 2m(2). Ladder type heat exchanger was used in the heat exchanger mode to transfer heat energy from collector to the water. The average particle size of 25nm and lower volume fraction of 0.05% were considered for the experimental study. Experiments were performed with and without polyvinyl pyrrolidine (PVP) used as the surfactant. The flow rate of nanofluid was varied from 1 lpm to 3 lpm and the efficiency was calculated as per ASHRAE standard. The experimental result revealed that the utilization of CeO2/water nanofluid with flow rate of 1.5 lpm in heat exchanger mode increases the collector efficiency by 24.2% than conventional mode and the CeO2/water nanofluid is suitable for improving the performance of flat plate solar water heating system.
