四种交叉V型吸热板-底板太阳能空气集热器热性能的数值模拟对比分析
Numerical Simulation Study on Thermal Performance of Four Cross-V-Groove Solar Air Collectors
摘要
Abstract
As one of the most commonly used flat plate air collectors,V-groove solar air collec-tor has been widely applied and studied in recent years.Based on solar load model,this paper used FLUENT to conduct three-dimensional numerical simulation on thermal performance of V-groove solar air collectors,whose length is 2 meters and 1 meter's width,V-groove plate has the same geometry size,with four types' flow channel at 30° tilt angle and the same air flow rate 60 m3/h.On the basis of the research,several results have been achieved:the temperature field of different section of absorbing plate,Nusselt number in the center of 0.5 m width absorbing plate section alone the length direction and instantaneous efficiency. Moreover,the analyses on the results showed that the instantaneous efficiency of structure is highest when V-groove ab-sorbing plate of air collector was horizontally placed and bottom plate longitudinal placed.The research provided innovative thoughts & reference and theoretical foundation for the design of solar air collector and engineering application.关键词
