Analysis of Heat Transfer and Lifting Force in a Ferro-Nanofluid Based Porous Inclined Slider Bearing with Slip Conditions

Abstract

Thermal effects have been investigated in a porous inclined slider bearing together with the slip boundary conditions. Using Jenkins model, the governing system of equations pertaining to the flow is solved analytically to yield the various bearing characteristics. The expressions for mean temperature, pressure and the lifting force (load carrying capacity) have been derived as a function of slip, magnetic, permeability, material and thermal parameters. Furthermore, the term pertaining to the co-rotational derivative of magnetization is expected to influence the lifting force significantly. Therefore its effect on the bearing characteristics is also considered. The lubricant is assumed to be incompressible, and its viscosity varies exponentially with the temperature. The behavior of mean temperature with other bearing characteristics across the fluid film thickness has also been investigated. The variations in the lifting force and mean temperature w.r.t. various bearing parameters have been analyzed graphically.
