Turbulence, instability and aeroacoustic sound

Turbulent flows contain structures that evolve across a wide range of scales. Some of these structures are linked to instability mechanisms and can organise the velocity and pressure fluctuations that contribute to sound.

A central question for the lab is how these dynamics can be identified and interpreted. A central aim is to connect measurable flow patterns to the physical processes that sustain them, and to examine how those processes relate to aeroacoustic sound generation.

This requires a combination of measurements, numerical data and analysis methods that can distinguish coherent dynamics from broadband turbulent motion.
