Masters of Flow Visualization: Master Class in Lagrangian Particle Tracking

Abstract

The event will begin with master classes given by experts in the relevant fields or “chefs”, on 6 selected flow visualization techniques (categories). Afterwards, the participants will use their pre-existing skills and experience in flow visualization in combination with the newly gained knowledge from the master classes to perform the experiment. Participants are organized in teams of three. They will perform a practical experiment relating to the selected flow visualization technique from the master class. An expert committee will evaluate and rank the result presented by the participants on each category. Technical skills shown during the experiment as well as scientific creativity for the visualization will contribute to the overall assessment. The Lagrangian Particle Tracking part consisted of a 30 minutes introduction to the measurement technique and the investigated flow. A water jet experiment was setup, with three cameras imaging a starting jet flow, seeded by 50 micrometer vestosint particles, which were illuminated by an array of whilte LEDs. The participants recorded data in the first 30 minutes and had another 30 minutes of time to produce a visualization animation of the staring vortex.
