Topic:  Turbomachinery Aeromechanical Modelling

内容简介:

Introduction:

Modern gas turbine design continues to move towards improved performance, reduced weight and reduced cost. As turbomachinery blade aerofoils are thinned to improve performance and reduce weight, aeroelastic issues such as flutter, forced response and stall driven vibrations become more predominant. Moreover, as the use of blisks (blade integrated-disks) with very low mechanical damping becomes more common in modern compressor designs, accurate prediction of compressor aeroelastic stability in a multi-row environment becomes vital. In this talk I will present a brief review of turbomachinery aeromechanical modelling methods and their challenges, with the focus on flutter.The aim is to summarise the unusual aeroelastic issues that we have observed in fans and multi-stage compressors. The focus of this talk is on flutter and blade passing forced response is not addressed here as their existence can be detected by a Campbell diagram.

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叶级叶片颤振的研究。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.
