太阳能烟囱中风压式通风装置的三维非定常数值模拟
Three dimensional unsteady numerical simulation of the wind pressure ventilator in solar chimney
摘要
Abstract
By establishing the physical model of the wind pressure ventilator in solar chimney,the three-dimensional unsteady numerical simulation of the wind pressure ventilator was carried out by using the Fluent simulation software,and the flow field characteristics and performance parameters of the device were obtained.The results show that when the wind wheel diameter is 10 m and the height is 15 m,the ventilator can produce a negative pressure of 64.5 Pa at the rotational speed of 69.3 r/min under equilibrium condition;the velocity field and pressure field of the specific cross section under different azimuth angles show obvious differences,and the flow field in the wind pressure ventilator is more complex;the blade torque of the wind pressure ventilator changes cyclically,and the total torque of the fan blades has not changed much with azimuth angle.The total torque of the H-type vertical axis wind wheel blades increases first and then decreases in a cycle to achieve a dynamic balance roughly.关键词
