Mechanism of Internal Polishing for Tubes Utilizing Magnetic Responsive Functional Fluid

Abstract

In this study, we investigated the effects of magnetic field distribution on the polishing inner surface of a tube utilizing MCF (Magnetic Compound Fluid) and discussed the polishing mechanism from the viewpoint of hydrodynamics. In the polishing, we filled the MCF involved abrasive particles in the tube and applied a rotational magnetic field vertically to the tube axis. In order to clarify the polishing mechanism, we conducted on the optical observation of the abrasive particles' behavior and measured the pressure distribution on the inner surface of the tube hydrodynamically.
