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. In this work, fluid dynamics analyzes were performed for six flat plate vacuum absorbent designs to improve temperature distribution and heat generation to improve thermal performance, variable as axial and radial speed, pressure distribution, function of flow, etc. The interpretation 4 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 version 4 of the flat absorbent plate is optimal for better heating.
