LOCAL ISOTROPY IN WIND TUNNEL TURBULENCE.
Abstract
Experimental evaluation of the longitudinal turbulent spectrum in the boundary layer of a long test section wind-tunnel is reported. The spectra agree very close with spectra reported for water flow in an ocean tidal channel and also for air flow over the sea surface. The spectra all agree with the predictions of local isotropy. The data reported were taken in a flat plate boundary layer at a station 69 feet from the tunnel entrance. The free-stream velocity was 30 feet per second. These flat plate boundary layer spectra differ greatly from previous data reported for flows with much small length dimensions. (Author)
