PhD studentship: Evaluation of Vortex Shedding of Slender Structures (updated)
Overseas applicants are also welcome to apply (We aim to do our best to attract the very best international students).A PhD studentship is available in the AFM research group, University of
Southampton, which fully covers University tuition fees (at EU/UK level**)
and provides a tax-free bursary of £16,000 per year for a 3.5-year
duration.
Project description:
Vortex shedding is a critical design consideration for slender structures such
as long-span bridges, high-rise buildings and tele-communication masts.It can
create large responses at relatively low wind speeds, leading to serviceability
and fatigue concerns.Since vortex shedding is highly sensitive to the precise
shape of the object, there are no established codes or standards that provide
adequate evaluation of vortex shedding risks.
The aim of this project is to address the problem of the control of vortex
shedding from a slender bluff body, and to develop a novel computational
approach that will be available for use by Arup (http://www.arup.com/) on
relevant bridge and building projects.It is anticipated that this tool will be
used in early stages of a project to assess vortex shedding risks, which may be
confirmed through wind tunnel testing at later stages.
Large Eddy Simulation (LES) and its derived varieties, e.g. hybrid LES, are the
most promising tool for computing unsteady three-dimensional flows at high
Reynolds numbers, and will be used in the project.To adequately capture fluid
structure interaction “dynamic meshes” (or known as “moving meshes”) will be
used as one of the major novel tools for this project.An LES model implemented
in an open-source computational fluid dynamics code will be used. The AFM group
has obtained excellent expertises and is a leading group in these areas.
This is an EPSRC CASE (Collaborative Awards in Science and Engineering)
collaborative PhD project between Arup and University of Southampton. Arup (a
global leading firm in engineering, design, etc) will act as the industrial
supervisor. The successful applicant will be based predominantly at the
University and will spend a minimum of 3 months working at Arup over the course
of the project.
UK applicants (UK citizen or have settled resident status) are eligible for
full funding.EU and Overseas applicants are also welcome to apply (We aim to do our best to attract the very best international students). If you are not sure for this please contact Dr
Zheng-Tong Xie z.xie@soton.ac.uk or have a look here,
http://www.epsrc.ac.uk/funding/students/Pages/eligibility.aspx.
Entry requirements: Candidates will have a first class or upper second class
degree (or its equivalent) in relevant disciplines, e.g. Applied Mathematics,
Engineering and Physics.
The successful candidate will work with a group of highly motivated, first class
research students in the areas of computational fluid dynamics, fluid-structure
interactions.
How to apply: Please send by email to Dr Zheng-Tong Xie, z.xie@soton.ac.uk.
Please ensure you include a short personal statement in your application,
stating why you particularly want to do a PhD, why you think you are suited to a
research degree and what particularly attracts you to this project.
