VISCOSITY VARIATION EFFECT ON THE MAGNETIC FLUID LUBRICATION OF A SHORT BEARING

Abstract

The performance of a magnetic fluid based short bearing is examined with the effect of viscosity variation. The pressure temperature relation of Tipei (1962) concerning viscosity variation is adopted here. The Neuringer-Rosensweig’s model has been considered for the magnetic fluid flow. The related modified Reynolds type equation is solved for the calculation of pressure distribution leading to the computation of load bearing capacity. The graphical representations indicate that the positive effect of viscosity variation gets aided considerably by the ferrofluid lubrication.
