A time series of particle image velocimetry data showing the behavior of a turbulent boundary layer on a zero-pressure gradient flat plate.

This gif is a series of images showing a turbulent boundary layer that has developed on a flat plate in a wind tunnel. The images were captured using a particle image velocimetry technique that involves a flow seeded with smoke particles, a laser sheet parallel to the flow, and a high speed camera that captures a double frame to calculate velocity vectors of the flow. The colors indicate velocity magnitude ranging from 25 m/s in red down to approximately 13 m/s in magenta.
