About the project

At the heart of Dyson products, such as vacuum cleaners, hair dryers and hand dryers, is an efficient high-speed fan for providing high flow rates at large pressure. However, like most fans they are also noisy.

This project is predominantly an experimental study into the investigation into the mechanisms of noise generation from this latest generation of high-speed fans. Particular emphasis will be given to ‘installation effects’ on the noise. Compared to their uninstalled levels, their noise is known to increase once installed in the machine. This is because air passing through the fan, after flowing through the machine, becomes disorted and turbulent.

The project will use state-of-the-art measurement techniques. These will characterise noise and flow with the objective of understanding the noise-generating mechanisms, and hence provide solutions for its mitigation. The experiments will take place on a new fan rig designed and built by Dyson at the University of 雅虎体育直播_中国竞彩网-中文app官网.

The successful PhD candidate will join the Acoustics group at the Institute of Sound and Vibration Research (ISVR). The ISVR is recognised as one of the world’s leading centres for the investigation of sound and vibration phenomena
