Acoustics

This work is about the study of the interaction between acoustic waves and flow structures, vorticity in particular. Non stationary vortices emit sound, and scatter sound when insofied by an incoming wave. Two areas are investigated experimentally:
- the measurement of vorticity unsing ultrasound scattering, as a time resolved acoustic spectroscpy technique,
- the analysis of the interaction between a single isolated vortex and an incoming sound wave.
