Spatial and temporal turbulent velocity and vorticity power spectra from sound scattering
arXiv:nlin/0408029 · doi:10.1103/PhysRevE.71.045601
Abstract
By performing sound scattering measurements with a detector array consisting of 62 elements in a flow between two counter-rotating disks we obtain the energy and vorticity power spectra directly in both spatial and temporal domains. Fast accumulated statistics and large signal-to-noise ratio allow to get high quality data rather effectively and to test scaling laws in details.
