| 摘 要： | 采用非定常薄层Navier-Stokes紊流运动方程来描述一跨声轴流压气机中径处的二维转-静非定常流场，速度脉动的相关分析表明转子尾迹对静子的热流流场几乎没有什么影响，而粘性的影响取决于叶片排之间的轴向距离。

| Abstract: | A two-dimensional unsteady,viscous aerodynamic analysis has beendeveloped for the flow inside a transonic single stage compressor.The analysis is based on a numerical method for solving the two-dimensional thin-layer Navier-Stokes equations for unsteady viscous flow through rotor-stator blade rows.The B-L turbulent model is applied for the turbulence closure.The dynamic grid method is used for the connection of rotor and stator grids.The velocity fl uctuation correlation analyses show that the potential flow field inside the stator is not influenced by the rotor wake passing,but when the gap of rotor-stator is decreased,the rotor wake will affect the stator boundary layer. |
