Abstract

A facility for electromagnetic boundary layer flow control employing conductive particle seeding is in the initial stages of development, fabrication and testing. The facility consists of three integrated components: a conductive particle seeding mechanism, an ionization plate and a Lorentz force generator plate that comprises of a series of flush-mounted surface electrodes and embedded rare earth magnets. Initial bench-top testing is reported with the future intention of testing the facility in the low speed and supersonic flow regimes. An aqueous salt solution reduced the voltage required to create a corona discharge by the ionization plate. The ionization of seeded air by an electric field presents several problems, notably an increased tendency for arcing as the conductivity within the boundary layer increases. The aqueous salt solution was accelerated or decelerated by the Lorentz force generator depending on the electromagnetic configuration. The benchtests demonstrated the ability of raising the conductivity of air to enable Lorentz force actuation under normal atmospheric conditions.
