| 摘 要： | 采用附壁点模型及控制面模型分析射流附壁模型,推导出附壁半径,以及对应各种位差时的附壁距离的计算方法.编程对10PXH,30PXH隙控式全射流喷头射流元件的附壁半径、附壁距离进行了初步计算,计算结果与实际采用的结构尺寸基本吻合,可以用来指导射流元件的结构设计.并利用木村模型对射流核心区域的流动进行了分析,核心区域的计算结果表明射流元件内附壁现象基本上发生在初始段内.

| Abstract: | The wall-attachment radius and distance as function of offset ratio were deduced by using attachment point model and control volume model.A computer program was written and applied to calculate the wall-attachment radius and the distance of fluidic component of fluidic sprinkler controlled by clearance typed 10PXH and 30PXH.The calculating result coincides with the actual size of sprinkler approximately,which indicates that the calculating method could guide the geometric design of fluidic component.The flo... |
