Description
-----------

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 
noise levels.

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.


Start date
----------
A start date of October 1st is desirable.


Candidate attributes
--------------------

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.


Applications
------------

Formal applications need to be made through the job-opportunities pages 
of the Faculty of Engineering and the Environment at the University of 
Southampton:
