چکیده
In this study, a solar cavity heat receiver for 36 m² two-axis parabolic dish collector has been designed, analyzed by employing computational fluid dynamics (CFD), manufactured in local workshop, and then tested experimentally on site. The is an open type with diameter of 624mm depth 665mm steel pipe spiral tubing helical at the bottom. concentrated sunlight focal point was found to be 200 mm as result optical analysis perfect mirror surface approach. CFD model receiver, assuming actual boundary conditions such volumetric flow rate, input temperature circulating water line pressure showed that analyses approached process, also process indicated can improved taking into account thermal radiation. Since period approximately 30 minutes system steady-state characteristic during daytime, set experimental measurements were carried out. It analytical outlet 1.07% higher than measured temperature, numerical 0.15% result.
