Abstract

A phase-averaging technique was employed to study the evolution of flow behind an oscillating bluff plate immersed in a flat-plate turbulent boundary layer. The experiments were performed for a reduced frequency of 0.0044. The large-scale disturbance generated by the plate developed to an organized form over 20 maximum plate height and then diffused rapidly, as quantified by the ratio of Reynolds stress of the phase-averaged fluctuation to that of the total fluctuation. The small-scale fluctuations embedded in the large-scale disturbance were almost removed by phase averaging. However, their contributions in Reynolds stress and kinetic energy were pronounced along the path of the core of the large-scale structure.
