Novel designs of cavity receiver for a solar parabolic dish concentrator

Abstract

To enhance the performance of a parabolic dish concentrator, it must achieve the maximum thermal performance of the receiver. Hence the optimization of the receiver performance will play an essential role in optimizing the system of solar parabolic dish concentrator. Lot of studies investigated many configurations and designs for receivers and compared the performance among them. Study of new and novel designs will enrich this field of study and pave the road to reach optimal receiver. The objective of this study is to develop the existing design further towards the best design. Cavity receivers, especially conical receivers are known for high thermal efficiency. This study investigate four designs of conical receivers, three of them are novel designs using Ansys Fluent software. The investigated receivers are helical conical, pentagon conical, rectangular conical, and triangle conical respectively in the order of their performance. At 300 K the thermal performance of the best receiver which is helical conical is 66.68%, and the optical efficiency are 89.2%.
