Active Control of Vortex Induced Vibration by Plasma Actuation

In this paper, the results of experiments on the elimination of vortex induced vibration (VIV) of a cylinder in cross-flow by using a simple active control method are reported. Motivated by new research, a Single Dielectric Barrier Discharge (SDBD) plasma actuator is used and the effect of steady and unsteady actuation demonstrated. The feasibility of the model parameters estimation was also studied in simulations by investigating the Fisher Information Matrix and the nonlinear numerical curve fitting methods applied to estimate identifiable parameters from experimental data. The efficiency of the control methods was found to be acceptable and simulation outcomes supported the experimental results.Copyright © 2010 by ASME
