Pressure fluctuations arising from turbulent flow can lead to excitation
of flexible structures, such as panels and windows of cars and
aeroplanes, and result in the generation of vibrational sound. This so
called aero-vibroacoustic mechanism of noise generation mechanism can
lead to passenger discomfort and sonic fatigue. Therefore, a detailed
understanding of the fully coupled fluid-structure-acoustic interactions
is required in order to devise successful strategies for controlling the
To date, this problem has mainly been investigated experimentally
lacking sufficient temporal and spatial resolution to get a highly
accurate picture of all important mechanisms, or using numerical
simulations relying on some form of turbulence modelling, with their
associated uncertainties in prediction accuracy.
In the current project, fully coupled high-fidelity fluid-structure
simulations will be conducted of configurations representative of those
encountered in automotive and aeronautical applications. An in-house
code specifically developed for high performance on supercomputers will
be used for this research. The data from these simulations will then be
used to develop and validate a novel flow-control framework in order to
derive successful passive and active noise-control techniques.
The successful applicant will join a vibrant research group with a large
number of PhD students investigating turbulence and noise problems.
A start date of October 1st is desirable.
Applicants should have a first class degree (or equivalent) in
Engineering, Maths or any other relevant fields.
THE STUDENTSHIP IS ONLY AVAILABLE TO UK/EU STUDENTS - overseas students
need to cover the additional fees themselves in order to be considered.
Formal applications need to be made through the job-opportunities pages
of the Faculty of Engineering and the Environment at the University of
