Rheodynamic Lubrication of a Rectangular Squeeze Film Bearing with an Exponential Curvature Variation using Bingham Lubricants
The present work deals with analyses of the effects of bearing curvature and non-Newtonian characteristics on the load capacity of an exponential rectangular squeeze film bearing using Bingham fluids as lubricants. Bingham fluids are characterized by an yield value and hence the formation of a “rigid” core in the region between the plates is justified. The flow is confined to the region between...
متن کاملMagnetic 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...
متن کاملBoundary lubrication: dynamics of squeeze-out.
The dynamics of the expulsion of the last liquid monolayer of molecules confined between two surfaces (measured recently for the first time) has been analyzed by solving the two-dimensional Navier-Stokes equation combined with kinetic Monte Carlo simulations. Instabilities in the boundary line of the expelled film were observed. We show that the instabilities produce a rough boundary for all le...
متن کاملJenkins 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...
متن کاملSqueeze-film Lubrication of the Human Ankle Joint: a Simplified Analytical Model during Walking
The aim of this paper is to propose an analytical approximate squeeze-film lubrication model of the human ankle joint for a quick assessment of the synovial pressure field and the load carrying due to the squeeze motion, considering both normal and pathological behaviour. The model starts from the theory of boosted lubrication for the human articular joints lubrication (Walker, et al., 1968; Ma...
