Numerical simulation of baffled baffle plate solar air collector
摘要
Abstract
In order to improve the efficiency of the heat collector of the solar air collector, this paper proposes a folded baffled solar air collector to increase the heat collector area, enhance the air flow and heat transfer effect in the flow channel. The influence of different folding angle (60,90,120 degree) of baffle plate on collector efficiency is obtained through numerical simulation, and when the folding angle of the baffle plate is 60 degree, the parameters of collector efficiency, heat loss coefficient, heat transfer factor and pressure loss of the collector under the conditions of different baffle plate space and inlet wind velocity of collector are obtained. The study results show that at the inlet temperature is 278 K,the environmental temperature is 274 K and the inlet wind velocity is 2 m/s, if the folding degree is 60, the maximum inlet temperature is 350.35 K, the maximum heating efficiency is 55.47% , and when the baffle plate space is 350 mm. The heat efficiency and the transfer factor of the baffle is the maximum, are 57.34% and 0.595 namely.关键词
