摘要
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 a large signal-to-noise ratio allow us to get high-quality data rather effectively and to test scaling laws in details.
