Nonlinear state-space modelling of the kinematics of an oscillating circular cylinder in a fluid flow

The flow-induced vibration of bluff bodies is an important problem of many marine, civil, or mechanical engineers. In the design phase of such structures, it is vital to obtain good predictions of the fluid forces acting on the structure. Current …

System identification of the kinematics of an oscillating cylinder using wake velocities

A classical problem in vortex-induced vibration is to know the flow field past an oscillating cylinder. In this paper we use system theory to identify the oscillatory behaviour of a circular cylinder from flow variables in the wake. We use numerical …
