Jenkins Model Based Ferrofluid Lubrication of a Curved Rough Annular Squeeze Film: Effect of Slip Velocity

Abstra t. This paper analyzes the ombined e e t of slip velo ity and transverse roughness on the performan e of a Jenkins model based ferro uid lubriation of a squeeze lm in urved rough annular plates. The slip model of Beavers and Joseph has been invoked to evaluate the e e t of slip velo ity. In order to nd the e e t of surfa e roughness the sto hasti averaging model of Christensen and Tonder...

Effect of slip velocity and roughness on the performance of a Jenkins model based on magnetic squeeze film in curved rough circular plates

An endeavour has been made to study and analyze the performance of a Jenkins model based ferrofluid squeeze film in curved rough circular plates considering the effect of slip velocity. The slip model of Beavers and Joseph has been used and Christensen and Tonder’s stochastic modeling of roughness has been employed. With the aid of suitable boundary conditions the associated Reynolds type equat...

Shliomis model based magnetic fluid lubrication of a squeeze film in rotating rough curved circular plates

Magnetic fluid lubrication of porous pivoted slider bearing with slip and squeeze velocity

In this paper the problem on “Magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by N Ahmad et.al.[7]” has been recapitulated using Jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. It is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (Refer equation(2.2)). This paper re...

Ferrofluid lubrication of circular squeeze film bearings controlled by variable magnetic field with rotations of the discs, porosity and slip velocity

Based on the Shliomis ferrofluid flow model (SFFM) and continuity equation for the film as well as porous region, modified Reynolds equation for lubrication of circular squeeze film bearings is derived by considering the effects of oblique radially variable magnetic field (VMF), slip velocity at the film-porous interface and rotations of both the discs. The squeeze film bearings are made up of ...
