| 摘 要： | 基于计算流体力学软件FLUENT，采用拉格朗日法，提出了一种求取旋转部件表面水滴收集系数的方法，并采用用户自定义函（UDF）予以实现。将该方法运用于发动机旋转整流帽罩的水滴撞击特性研究，结果表明：随着帽罩锥体锥角及转速的增大，帽罩表面的局部水收集系数沿其表面外形线下降较快，且撞击区域变小。

| Abstract: | Based on the Computational Fluid Dynamics software FLUENT,a Lagrangian method is presented to numerically simulate supercooled droplets impingement on the wall of rotating components by employing user defined function(UDF);the method was applied to study the impinging characteristics of the rotating fairing of aero-engine.The computational results indicate that as the cone angle and the rotating speed grow,the collection efficiencies fall rapidly and the impingement limits become small along the surface. |
