Catalogue data

Abstract	This is a laboratory-based course on imaging techniques for the measurement of fluid flow properties. Modern approaches are presented, including particle image velocimetry and particle tracking velocimetry, applied in various experimental facilities. Students obtain first-hand experience with such techniques in laboratory sessions, using high-speed/high-resolution cameras in wind/water tunnels.
Learning objective	Knowledge of the working principles of modern flow imaging and velocimetry Understanding of hardware and software requirements to achieve desired spatio-temporal resolution. Ability to carry out imaging experiments in actual laboratory flows, and interpreting meaningfully the results.
Content	Basics of optical diagnostics. Conception of laboratory flow experiment to be characterized by imaging, with focus on the spatial and temporal scales at play. Laboratory experiments including: - characterization of vortex shedding by wake visualization and liquid crystal thermography. - Eulerian flow field in turbulent flow by particle image velocimetry - Lagrangian flow field in turbulent flow by particle tracking velocimetry - fluid-structure interaction in wind tunnel by high-speed imaging.
Lecture notes	Handouts will be made available.
