Experimental investigation of the rough bottom turbulence structure above a rough bottom

The time and space-time correlation functions in a rough-bottom test tank were measured. Eulerian turbulence scales, subsequently used for determining space scales L calculated on the assumption of validity of the Taylor theorem, are obtained from one-point measurements of velocity fluctuations obtained by a hotwire anemometer array. The longitudinal dimensions of turbulent inhomogeneities at two levels were determined from two-point recordings.
