Investigation into the noise from small packaged compressors

该项目是对小型高速风扇的噪声产生机制及其安装在商业产品（如吹风机和真空吸尘器）中的影响的基础研究。该项目主要是实验性的，旨在建立封装驱动损耗和辐射噪声之间的联系。该项目将集中在一个新的管道钻机。该项目的一个关键部分是开发测量和消除噪声以及消除压气机叶片附近的平均流和湍流所需的测量技术。

This project is a fundamental study into the noise generation mechanisms of small high speed fans and the effects of its installation within commercial products, such as hairdryers and vacuum cleaners. This project, which is predominantly experimental, aims to establish the link between package driven losses and the radiated noise. The project will be centred on a new ducted rig. A key part of this project will be to develop the measurement techniques required to measure and characterise the noise as well as to characterise the mean and turbulent flow in the vicinity of the compressor blades.
