摘要

为了提高太阳能腔式颗粒吸热器的热效率，设计了腔体式石英螺旋管太阳能颗粒吸热器，建立流动分析模型，并对吸热器结构参数进行对比分析，最终将腔体锥度定为5°，管道螺旋圈数定为5圈，采用石英玻璃窗口；在确定吸热器参数后，对该吸热器的传热特性进行数值模拟，探究了不同入射辐射强度和不同颗粒流量对该吸热器传热特性的影响规律。结果表明：在入射辐射强度为100 000～350 000 W/m~2、颗粒流量0.001～0.051 kg/s范围内，出口端颗粒最高温度673℃，吸热器的最高效率为70.12%。该研究对高温太阳能颗粒吸热器的设计具有参考意义。

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/m~2 to 350 000 W/m~2 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.
