An experimental investigation into forced separated flow shear layer instabilities and their effect on a separating-reattaching flow

The research involved developing a model to conduct flow separation experiments in a water tunnel. Results were collected using planar laser imaging fluorescence and a four-camera particle image velocimetry technique, which measured different aspects of the separated and reattached fluid flow. The experiments identified frequencies more susceptible to manipulation by a perturbation, helping to minimize the extent of reversed flow. Various perturbation strengths were tested, showing how the extent of separation varied based on the initial strength of the perturbation and its frequency.
