• THE EFFECT OF MHD AND COUPLESTRESS FLUID ON THE PERFORMANCE CHARACTERISTICS OF WIDE SLIDER BEARING WITH AN EXPONENTIAL AND SECANT FILM PROFILE –A COMPARATIVE STUDY

Abstract

The theoretical investigation of comparative study between the performance characteristic of Magnetohydrodynamic wide slider bearing with exponential and secant film profile lubricated with couplestress fluids is made. On the basis of Stokes micro-continuum theory, the modified Reynolds equation is derived and closed form expression for fluid film pressure, load carrying capacity, frictional force and coefficient of friction is obtained.  The graphs depicting the build-up between load carrying capacity, frictional force and coefficient of friction is plotted. Computations reveal that, exponential slider has significant load carrying capacity and friction as compared to secant slider. To illustrate the use of present study for engineering application, a design example of slider bearing lubricated with an electrically conducting fluid is also presented.
