| 摘 要： | 通过建立压差控制病房模型,模拟渗透风量随压差及门缝特性变化状况,确定不同门缝高度、门高度及门厚度值下,门缝渗透函数中的相关参数.模拟结果对比显示,门缝渗透函数的流量系数与门缝高度呈线性关系,并随着门宽度的增加而减小,而门的厚度在一定范围内对流量系数的影响可忽略不计.在此基础上得出适合压差控制隔离病房密闭门的渗透函数及渗...

| Abstract: | With the model of pressure monitor ward was built,the relationship between air infiltration flux through cracks under door and pressure difference was simulated and the flux coefficient in infiltration function of the door crack was obtained based on CFD.According to the simulation results,the flux coefficient is linear with the crack height and decrease as the width of the door increase,but the influence of the thickness to the flux coefficient can be ignored.The infiltration function and flux coefficient ... |
