Abstract

A closed-loop control algorithm has been developed for suppressing the vortex shedding of flow past a circular cylinder in an electrically low-conducting fluid (e.g. seawater). The intent is to avoid both vortex shedding and flow separation from the body, which is achieved through the introduction of localized electromagnetic forces (Lorentz forces) generated by an array of permanent magnets and electrodes on the surface of the circular cylinder. More specifically, the closed-loop control has been derived from the equations capable of determining at all times the intensity of the Lorentz force in order to control the flow. This is accomplished first, independently of the flow (open loop algorithm) and second, based on some partial flow information measured on the surface of the solid body.
