English Abstract

Hot-wire anemometry techniques were used to investigate wall turbulence for boundary layer flow over a flat plate. The anemometer signals were visually analysed to bobtain the frequency of occurrence of the burst process. Both fully turbulent and transitional turbulent flows were studied with emphasis on the latter. It was observed that the burst period, measured at a point off the wall, increases to infinity as the Reynolds number decreases and approaches laminar conditions. The results obtained are in basic agreement with off-wall literature data for fully turbulent flow. As for the transitional region data, none are available for comparison.
