Abstract

An experimental study is carried out to investigate the unsteady pressure exerted on the surface of a round cylinder in the subcritical Reynolds number range. Results are presented for the surface pressure fluctuations, spanwise coherence, lateral correlation length, and peripheral coherence. Discussions are provided for the dominance of the first three vortex shedding tones at different regions of the cylinder and the size of the flow structures around the cylinder. The dataset provided have shed new light on the unsteady aerodynamic loading acting on cylinders and provides the impetus for further research on the aerodynamics and aeroacoustics of bluff bodies.
