Universal Dynamics in Flow-Induced Cable Vibration

A combined analytical-experimental approach is used. Analytical aspects focus on the continued development of a low-order model that utilizes a series of diffusively coupled circle map oscillators along the cylinder span. This coupled map lattice has been extended to include control logic to develop a very efficient low order model for control studies in cylinder wake flows. On the experimental side our recent focus has been on development of a novel, non-intrusive circulation measurement technique which yields spatial lift distributions along the span of an oscillating bluff body.
