On the efficiency of MHD drag reduction
Shatrov, V.; Gerbeth, G.;
Recently, permanent magnets and high electric current densities are often used to achieve reasonable Lorentz forces for a magnetohydrodynamic (MHD) flow control. This choice, however, usually leads to a low energetic efficiency for the flow control of seawater. We present results of direct numerical simulations of turbulent channel flow drag reduction using electromagnetic forces. The Lorentz force is created by a permanent magnetic field and an electric current from electrodes placed at the bottom wall. The investigations are restricted to the two cases of a spanwise oscillating force and a streamwise steady force. The lecture to be presented extends the results recently published by the authors.
