Modeling a Porous Slider Bearing With an External Reservoir

This work considers a porous slider bearing above an external reservoir. The bearing system consists of a lubricating film, porous medium, and a reservoir. The Darcy model is used for flow inside the porous medium. The moving slider bearing establishes a pressure profile that circulates fluid between the lubricating region and the reservoir. Simplifications are made to allow for a semi-analytical solution to be constructed that can be easily solved using a standard computational package. It is shown that the fluid is circulated inside the bearing to allow for a load-carrying capability as well as for no external lubricant supply.Copyright © 2007 by ASME
