Design and heat transfer performance simulation of cavity solar heat particle receiver based on quartz spiral tube
摘要
Abstract
In order to improve thermal efficiency of the solar cavity particle receiver,this paper designs the quartz spiral tube solar cavity particle receiver with quartz spiral tube,and establishes flow model to conduct comparative analysis on the structural parameters of the receiver.Finally,the cone angle of the cavity is set to 5°,the number of spiral turns is set to 5,and quartz window is adopted.In order to analyze the heat transfer characteristics of this receiver,this paper studied the influence of different incident radiation intensities and particle mass flow on it.The results show that,within the range of incident radiation intensity of 100 000 W/m2 to 350 000 W/m2 and particle mass flow of 0.002 kg/s to 0.051 kg/s,the highest particle temperature at the outlet is 672℃,and the highest efficiency of the receiver is 70.12%.The research has reference significance for the design of high-temperature solar particle receivers.关键词
