PhD Studentship: Noise Generation Mechanisms of Dyson High Speed Fans

School of Engineering

Location:  Highfield Campus
Closing Date:  Friday 16 November 2018
Reference:  1060318DA

Project: ISVR-ACOUS-536

At the heart of Dysons’s 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 since the air passing through the fan, after flowing through the machine, becomes distorted and turbulent.  

The project will use state-of-the-art measurement techniques for characterising the noise and the flow with the objective of understanding the noise generation 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 Southampton.

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. Applications are invited from prospective UK candidates with an excellent degree (or an equivalent standard in other qualifications approved by the University) in a relevant mathematics, science or engineering subject. Strong mathematical skills will be an advantage.

The studentship will be fully-funded including paid tuition fees (UK/EU rate). We are fortunate that we are able to pay an enhanced tax-free stipend that is significantly greater than the standard rate.  Regular interaction with staff at Dyson is anticipated together with visits to the company.

Funding and Eligibility

This studentship covers home-rate tuition fees and provides an enhanced tax-free stipend.

This funding is only available to UK citizens or EU citizens who have been resident in the UK for at least 3 years prior to the start of the studentship and not mainly for the purpose of receiving full-time education. For further guidance on funding, please contact
