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

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.
