| Summary: | The utilization of the jet impingement technique is a prevalent approach in enhancing the efficiency of photovoltaic
thermal (PVT) collector through the augmentation of heat transfer rate. The present work introduces a novel
approach known as the reverse circular flow jet impingement (RCFJI) on a PVT collector. The performance analysis
of the PVT collector was assessed through the utilization of CFD simulation. The RCFJI was installed to a jet plate
which incorporates 36 holes. The holes were positioned at a spacing of 113.4 mm (x-axis) and 126 mm (y-axis). The
air outlet channel of the jet plate has been configured into four different configurations: one hole (1h), three holes
(3h), four holes (4h) and five holes (5h) to analyze the best outlet configuration leading to the highest energy
performance. The simulation evaluation encompassed a range of solar irradiance spanning from 600 W/m2
to 900 W/
m2
, while the mass fl ow rates varied from 0.01 kg/s to 0.14 kg/f for each geometrical design. Based on the research,
the configuration that records the highest efficiency was 1h. The maximum photovoltaic efficiency recorded was
11.38% at 600 W/m2
and mass fl ow rate of 0.14 kg/s. While the maximum thermal efficiency was 63.2% at solar
irradiance 900 W/m2
and mass fl ow rate of 0.14 kg/s. |
