Imaging in Fluid Dynamics
Last Updated: 2026-06-03 00:07:54
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.
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.

Core Courses (The Core Courses in the Master’s program Mechanical Engineering listed below are indicative and include courses designed by the Department at the Master's level. With the approval of the tutor, students may also select Master's-level courses offered by other departments at ETH. These courses will be marked as non-regular in the LAG, but their categorization as Core Courses is possible if included in the approved LAG.)
