    "abstract": "We investigate the vorticity dynamics in a turbulent vortex using scattering\nof acoustic waves. Two ultrasonic beams are adjusted to probe simultaneously\ntwo spatial scales in a given volume of the flow, thus allowing a dual channel\nrecording of the dynamics of coherent vorticity structures. Our results show\nthat this allows to measure the average energy transfer time between different\nspatial length scales, and that such transfer goes faster at smaller scales.",
