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 absorbing 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.
