 Control strategies for the reduction of vortex induced vibrations in marine risers

As a first step towards controlling vortex induced vibrations in marine risers, 2d incompressible flow around a circular disk is studied using computational fluid dynamics. The objective is to reduce the lift force on the disk by means of boundary control with actuation in the form of blowing and suction of fluid on the disk perimeter.
