Abstract
Both rotation and oscillation are intrinsically periodic. Such periodicity may be induced on a body through vortex shedding; or, if a body is forced to rotate or oscillate, vortex shedding can strongly influence the periodic characteristics of the flow. This paper discusses various degrees of analogies or similarities between rotating and oscillating bodies with vortex shedding in a parallel flow, with respect to both the physical phenomena involved and the mathematical modelling. The latter is performed with the aid of the nonlinear oscillator concept or, more realistically, by solutions of the field equations. It is argued that, qualitatively, a fifth-order polynomial for the damping term is necessary in the oscillator model to simulate vortex-shedding effects. The feasibility of solving the Navier-Stokes equations for those complex flow phenomena is demonstrated.
