MHD Electrolyte Flow within an Inter-electrode Gap Driven by a Sinusoidal Electric Field and Constant Magnetic Field

C. Bradley [1], J. Samuel [2],
[1] Benét Laboratories, U.S. Army RDECOM-ARDEC, Watervliet, NY, USA
[2] Department of Mechanical Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, Troy, NY, USA

PECM is a necessary extension to traditional ECM for some high-performance materials. Electrolyte flow in the inter-electrode gap (IEG) can be assisted using a magnetic field to allow higher currents, but this creates a magnetohydrodynamic flow. This paper presents a study of flow ...
