Flow Structures Associated with Turbulent Mixing Noise and Screech Tones in Axisymmetric Jets
A jet from an axisymmetric convergent nozzle is studied at ideal and underexpanded conditions using velocity and acoustic data. Two particle imaging velocimetry setups, a 10 kHz system and a multi-camera confi...

Active Flow Control for High Speed Jets with Large Window PIV
The current work investigates a Mach 0.6 jet flow field with particle image velocimetry (PIV) and simultaneously sampled near and far-field pressure. Two component velocity measurements are taken in the stream...
