DOI: 10.1103/physrevfluids.4.104601
Abstract: The energy cascade and diverse turbulence properties of active-grid-generated turbulence were studied in a wind tunnel via hot-wire anemometry. To this aim, two active grid protocols were considered. The first protocol is the standard triple-random… read more here.
