Title

MATHEMATICAL ANALYSIS OF NEWLY DESIGNED TWO POROUS LAYERS SLIDER BEARING WITH A CONVEX PAD UPPER SURFACE CONSIDERING SLIP AND SQUEEZE VELOCITY USING FERROFLUID LUBRICANT

Pages

  93-101

Abstract

 This paper proposes mathematical modeling and analysis of FERROFLUID lubricated newly designed slider bearing having convex pad (surface or plate) stator with two porous layers attached to the slider. The problem considers the effect of SLIP VELOCITY proposed by Sparrow et. al [17] and modified by Shah et. al [9] at the film-porous interface. The SQUEEZE VELOCITY V=-ḣ, which appears when the upper impermeable plate approach to the lower one, is also considered here for study. The magnetic field is assumed to be oblique to the lower plate. From the Reynolds’s equation of the above model, expressions for dimensionless form of pressure and load carrying capacity are obtained. The expression for the dimensionless load carrying capacity is then solved numerically to examine its possible effect on the designed bearing system from the results it is concluded that (1) when k1>k2 dimensionless load carrying capacity increases about 6.35% for both ḣ=0, and ḣ¹0 as compared to k1<k2. (2) the dimensionless load carrying capacity increases about 113% for both ḣ=0 and ḣ¹0 when k1=k2=0.0001 as compared to k1=k2=0.01. in the above results k1 and k2 represents the permeabilities of the upper lower porous layers (matrixes) respectively.
