An EPSRC CASE PhD Studentship: Evaluation of Vortex Shedding of Slender Structures (post filled)
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.
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 or resident status) are eligible for full funding. EU and overseas applicants may be eligible if they have a relevant connection to the UK (see 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.
