Abstract
This paper presents the design and experimental analysis of a static 3-D solar elliptical hyperboloid concentrator (EHC) for process heat applications. The 3-D static elliptical hyperboloid concentrator is designed to accept a wide range of incidence angles (+/- 30 degrees) and has a concentration ratio of 20 x for medium temperature applications (100-150 degrees C). Ray tracing analysis has been used to obtain, the solar flux distribution on the receiver aperture plane for the EHC configuration. The optical efficiency has been obtained theoretically using Optis (TM), a ray tracing program and optimisation has been carried out, before the design of the EHC was finalised and experimentally tested. The experiments were carried out for different conditions to study the performance of EHC. The experimental study has also been carried out to obtain the inlet and outlet temperature of a fluids supplied to a coil heat exchanger solar receiver.
