Abstract : The effect of oscillating flow on the turbulent intensity distribution in the turbulent boundary layer on a flat plate was investigated experimentally. A wind tunnel incorporating a set of rotating shutter blades downstream of the test section was used to create oscillating flow with amplitude variations from 6 to 110 per cent of mean velocity and frequencies ranging from 5 to 80 cycles per second at a local Reynolds number of 1,500,000. A vertical traverse of the turbulent boundary layer was conducted with a hot wire anemometer, and the mean velocity profile and the turbulent intensity distribution were recorded. (Author)
