Studies of the Wall Shear Stress in a Turbulent Pulsating Pipe Flow
… the imposition of a sinusoidal oscillation on a turbulent pipe flow. The amplitude of the oscillation is small enough that a linear response is obtained and the dimensionless frequency, (omega)('+), is large compared to that studied by most previous investigators. The most striking feature of the …
