题: 声反射对风扇和核心压气机叶片颤振的影响

Topic: Influence of acoustic reflection on flutter of fan and core compressor blades

内容简介:

Introduction:

报告主要讨论气动弹性不稳定性的一些工作,气弹不稳定性通常称为失速颤振,发生在部分转速工况下的失速边界附近。在本次报告会上还将展示进气道的声反射对于颤振稳定性的重要性,在设计风扇叶片时需要考虑。

1.风扇和压气机的气动和气动弹性不稳定性

2.声反射对风扇和核心压气机叶片颤振的影响

This seminar discusses the work on the aeroelastic instability, commonly called stall flutter, which occurs at part speed operating conditions near the stall boundary. It also will be shown in this seminar that the acoustic reflection from the intake is very important for flutter stability and needs to be considered during the design of a fan blade.

1. Aerodynamic and aeroelastic instabilities of fans and compressors

2.Influence of acoustic reflection on flutter of fan and core compressor blades

Speaker’s Biography

赵帆洲博士是英国帝国理工振动大学技术中心的副研究员。他于2017年在帝国理工获得博士学位。博士期间的研究工作是关于多级轴流压气机中间级叶片颤振的研究。赵博士目前的研究方向是风扇和压气机的颤振,多级压气机失速和喘振,以及和叶片振动相互作用的数值模拟。

 

Dr. Fanzhou Zhao is a research associate at the Vibration UTC, Imperial College London. He graduated from Imperial College in 2017 with a PhD degree on flutter of embedded blade rows in multi-stage axial compressors. Currently his research and interest are flutter of fans/compressors, stall and surge modelling of multi-stage compressors and their interaction with blade vibration, e.g. flutter in deep surge.
