Abstract

Squeeze film lubrication of a magnetic fluid between two approaching surfaces is considered in the presence of an externally applied magnetic field that is oblique to the lower surface. The upper one is a rigid rectangular smooth plate, and the lower one is a porous rectangular plate composed of three thin layers with different porosities. Explicit solutions for the velocity, pressure, and the load-carrying capacity are obtained. The time for the upper plate to come down is found to be longer than for viscous squeeze film. This shows that magnetic fluid-based squeeze film is definitely better.
