| 摘 要： | 为了测量静环端面安装传感器开孔对流场气膜压力的影响因子,应用Solidworks软件建立三维螺旋槽干气密封端面气膜模型,包括在动环槽底根径相对的静环端面开孔和不开孔的2种模型建模.在特定工况下,运用Fluent软件对螺旋槽干气密封内部微间隙三维气体流场2种模型以层流模式分别进行数值模拟,得到2种模型的泄漏量,且与试验值...

| Abstract: | In order to determine the factor of influence of the holes,which were opened on the end face of static seal-ring for installing the transducer,on the gas-film pressure of the flow field,the software Solid works was used to build up a gas-film model of three-dimensional spiral grooved gas face seals,including two models: one being with holes on the end-face of the static seal-ring at the position of root-radius of the moving seal-ring and the other being without holes.In a specified operational condition,the... |
