摘要
为了在不同太阳辐射强度下,太阳能烟囱能发挥最大的通风性能,本文提出了旋转集热板式太阳能烟囱模型;用Fluent软件对其通风性能进行数值模拟,研究两板底部宽度在100~300 mm、太阳辐射强度200~400 W/m^2、集热板旋转角度0°~14°时的通风性能;分析了烟囱内部温度场与速度场分布情况.模拟结果显示,在一定范围内,增大集热板旋转角度、增大两板底部宽度以及提高太阳辐射强度均能有效提高太阳能烟囱的通风性能.
In order to attain the optimal ventilation performance for solar chimney under the different solar radiation intensity,a rotating collector plate solar chimney model is proposed and the fluent software is used to simulate its ventilation performance.The ventilation performance of the two plates with the bottom width of 100 mm-300 mm,the solar radiation intensity of 200-400 W/m2 and the rotating angle of the collector plate at 0°-14°was studied.And the distribution of temperature and velocity field inside the chimney was analyzed.Simulation results show that the ventilation performance of solar chimney can be effectively improved by increasing the rotating angle of the collector plate,the bottom width of two plates and the radiation intensity within a certain range.
