摘要
对目前基层中队配备的典型移动正压送风机产生的流场进行全尺寸实验,研究了正压排烟风机在开敞环境中的流场特性;在FDS中通过正确的几何形状、通风口位置和边界条件对实验风机进行建模,将实验与模拟结果进行比对,发现平均差异均小于10%,验证了FDS风机模型的有效性。
A full-size experiment was carried out on the flow field generated by the typical mobile positive pressurized ventilator equipped with the current grassroots squadron to study the flow field characteristics of the positive pressurized ventilator in the open environment. With the correct geometry,vent positions and boundary conditions adopted in the FDS,the experimental ventilator conditions were modeled. The results of the experimental and simulation were compared and the average difference was less than 10%. The validity of the FDS fan model was verified.
