Summary on Grant Application Form |
|
Support is requested for the funding of a research project on the characterisation of the wake of a single cylinder placed on a stream with a periodic component superimposed upon it, using state of the art experimental techniques such as 3D PIV and 4 channel LDA. The project is of great fundamental and practical interest and it attempts to determine parameters related to the vortex dynamics and turbulence production in the wake of a circular cylinder under conditions of vortex shedding lock-on in a systematic manner using accurate and non-invasive techniques. The PIV technique will be used mainly to study the vortex formation process, possible vortex shedding patterns and associated vortex characteristics for a range of perturbation frequencies, amplitudes and Reynolds numbers. The LDA system will be used mainly for time-resolved and phase-averaged determination of the three velocity components and Reynolds stresses as well as spatial correlation measurements to accurately determine turbulence statistics by taking into account the contributions of both the periodic (due to vortex shedding) and random (turbulent) motions present in the flow. The proposed research is original, internationally competitive and offers good value for money since it involves a named researcher who is well trained on advanced optical experimental techniques and separated flows/vortex dynamics as well as significant contribution from the host organisation in terms of facilities and experimental equipment.
