Experimental studies of the structure of the Reynolds stress in a turbulent boundary layer on a smooth wall with zero pressure gradient are reported. The technique of conditional sampling is employed to study the signal, uv, obtained from hot wire probes in a x configuration. Measurements of the mean time intervals and durations of burst and sweeps are attempted. In the conditional sampling method the velocity at the edge of the viscous sublayer is used as a detector of bursts and the signal, uv, is obtained at various locations. Velocity is studied in relation to bursts and sweep events. Author
