On magnetohydrodynamic drag reduction and flow control behind a body
On magnetohydrodynamic drag reduction and flow control behind a body
Gerbeth, G.; Shatrov, V.
In the first part we present results of direct numerical simulations on turbulent channel flow drag reduction using electromagnetic forces. The Lorentz force is created by the interaction of a permanent magnetic field and an electric current from electrodes placed on the bottom wall surface. We consider the two cases of a spanwise oscillating force and a streamwise steady force. In the second part the flow behind an electromagnetically self-moved sphere is considered for which a drag reduction is found. Results on the linear and nonlinear flow stability will be provided.
Keywords: magnetohydrodynamic drag reduction; efficiency
