Abstract
In this paper, we investigated the combined effect of variable-viscosity, surface roughness, couple stress fluid, velocity-slip, and ferrofluid lubricant on the fluid-film characteristics of an infinitely wide rectangular plate squeeze-film bearing. The variable-viscosity is obtained using the Barus formula and the lubricant becomes non-Newtonian due to the combination of the couple-stress fluid and the ferrofluid lubricant. The Modified Reynolds equation is used to solve the pressure distribution, where an external magnetic field produces a body force in the lubricating system. We calculated the pressure distribution and the load-carrying characteristics of the squeeze film bearing. The results indicate that the slip-velocity enhances the pressure distribution and the load-carrying capacity of the bearing. For a combination of slip-velocity and Magnetic parameters, the load and pressure distribution are greatly enhanced.
