Abstract : An oscillating flat plate apparatus allows study of the periodic laminar flows of viscous fluids induced by the plate motion. The measurements and their comparison with parallel flow theory clearly show the periodic flow is a combination of oscillating flow and pulsating flow. The parameter for similarity predicted from the laminar theory seems justified, but above a critical frequency the flow becomes less regular. This parameter along is not adequate to describe the time-dependent flow. (Author)
