Full Project Details

An elastic structure can start vibrating when the speed of the flow in which it is placed exceeds a certain threshold: this phenomenon is called flow-induced vibrations. These vibrations can be harmful (fluttering of an aircraft wing) or useful (energy harvesting). The canonical well known configuration is that of a clamped-free elastic plate placed in an axial flow. However, no one knows how the instability of such a plate is modified when one departs from this ideal configuration: for instance, if both ends are clamped and if the structure is pre-deformed. In such a case the fluid-structure interaction can be difficult to model due to geometric nonlinearities and flow detachment.

The objectives of this thesis are: (i) to characterize the instability induced by the incoming flow on a pre-deformed plate, using a classical approach combining experimental and theoretical studies; (ii) to control this response by modulating the mechanical or geometric parameters along the plate. This topic has many possible applications in the fields of Automotive and Aeronautics (mechanical noise in vibration, fatigue…), and Energy Engineering (energy harvesting from winds).

Entry requirements

Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Physics or Mechanical Engineering or a related subject. A relevant Master’s degree and/or experience in one or more of the following will be an advantage: Applied Mathematics, Theoretical and Experimental Fluid Dynamics, Colloids and Interface Science.

Successful students will be notified by 30 September 2019.
