摘要

超临界二氧化碳动力循环在高温条件下运行时具备性能优势

且与塔式太阳能集热有很好的温度匹配。太阳能接收器在高温条件下工作时的传热和机械性能直接影响系统运行的安全性。为此

利用ANSYS Fluent和Mechanical软件对太阳能接收器的热力-机械性能开展研究。首先

分析了热流密度分布对集热管排热力-机械性能的影响。其次

将圆管排中性能较差的管替换为强化管

并对不同类型的管排进行整体性能分析。最后

研究了不同替换方案对管排性能的影响。结果表明:相较于圆管排

内螺纹管排的总熵产降低11.5%

总体热损失降低4.5%

替换后6号和12号管的等效应力降低14.9%;5-6-7-11-12-13管排的综合性能最优

相较于圆管排其总熵产降低44.7%

总体热损失降低25.2%

并且等效应力最大值低于圆管排;本研究为太阳能腔式接收器的设计和优化提供了理论依据。

Abstract

The supercritical carbon dioxide power cycle exhibits performance advantages when operating under high-temperature conditions

and it has a good temperature matching with tower-type solar heat collection systems. The heat transfer and mechanical performances of the solar receiver during high-temperature operation directly affect the operational safety of the entire system. Therefore

ANSYS Fluent and ANSYS Mechanical software was used to investigate the thermal-mechanical performances of the solar receiver. Firstly

the influence of heat flux density distribution on the thermal-mechanical performances of the heat-collecting tube bundle was analyzed. Secondly

the tubes with poor performance in the circular tube bundle were replaced with enhanced tubes

and a comprehensive performance analysis was conducted on different types of tube bundles. Finally

the effects of different replacement schemes on the tube bundle performance were studied. The results show that: compared with the circular tube bundle

the total entropy generation of the internally ribbed tube bundle is reduced by 11.5% and the overall heat loss is reduced by 4.5%

while the equivalent stress of No.6 and No.12 tubes after replacement is reduced by 14.9%. The 5-6-7-11-12-13 tube bundle achieves the optimal comprehensive performance—its total entropy generation is reduced by 44.7%

the overall heat loss is reduced by 25.2% compared with the circular tube bundle

and the maximum equivalent stress is lower than that of the circular tube bundle. This study provides a theoretical basis for the design and optimization of solar cavity receivers.
