Study on Enhancement of Thermal Performance of Absorber Flat Plate Solar Collector

Abstract

The main objective of this work is to improve the heat transfer rate by changing the design of the absorber flat plate and to compare the different results of computer-assisted fluid dynamics analysis for all designs.Fluid dynamics analyses were performed for six flat plate vacuum absorbent designs to optimise temperature distribution and heat generation, as well as variables such as axial and radial speed, pressure distribution, and thermal performance. , function of flow, etc. The interpreted design-3 is 15.339% more efficient than the basic design in terms of maximum temperature and thermal power, which was increased by 8.14% compared to the basic design. It is recommended that design 3 of the flat absorbent plate is optimal for better heating. The temperature distribution and heat generation for better thermal performance were checked and compared using computational fluid dynamics analysis for six designs of absorber plate for evacuated flat plate collectors.
