主 题：parabolic collector conical cavity receiver critical geometric parameters optical performance
摘 要：The optical performance of a receiver has a great influence on the efficiency and stability of a solar thermal power *** of the literature focuses on the optical performance of receivers with different geometric shapes,but less research is conducted on the effects of critical geometric *** this paper,the commercial software TracePro was used to investigate the effects of some factors on a conical cavity receiver,such as the conical angle,the number of loops of the helical tube,and the distance between the focal point of the collector and the *** factors affect the optical efficiency,the maximum heat flux density,and the light distribution in the conical *** optical performance of the conical receiver was studied and analyzed using the Monte Carlo ray tracing *** make a reliable simulation,the helical tube was attached to the inner wall of the cavity in the proposed *** results showed that the amount of light rays reaching the helical tube increases with the increasing of the conical angle,while the optical efficiency decreases and the maximum heat flux density *** increase in the number of loops contributed to an increase in the optical efficiency and a uniform light *** conical cavity receiver had an optimal optical performance when the focal point of the collector was near the aperture.
