Disturbed-laminar flow over an oscillating cylinder

Disturbed-laminar flow over an oscillating cylinder
Disturbed-laminar flow over an oscillating cylinder
The flow around a cylinder oscillating at small amplitude in fluid otherwise at rest is subject to instabilities that, at a certain amplitude, trigger a regime of three-dimensional disturbed-laminar flow. This paper discusses apparent conflicts that are evident in recent observations, and describes new measurements of hydrodynamic damping and flow visualisations. Attention is directed at the range 1,000 < b < 20,000 where b is the Stokes parameter based on the cylinder’s diameter.

Abstract

The flow around a cylinder oscillating at small amplitude in fluid otherwise at rest is subject to instabilities that, at a certain amplitude, trigger a regime of three-dimensional disturbed-laminar flow. This paper discusses apparent conflicts that are evident in recent observations, and describes new measurements of hydrodynamic damping and flow visualisations. Attention is directed at the range 1,000 < b < 20,000 where b is the Stokes parameter based on the cylinder’s diameter.
