Abstract

In this paper, the performance of the curved pivoted porous slider bearings is studied. The general modified Reynolds-type equation is derived on the basis of micro continuum theory. Microscopic effects generated by micromotions of particles in suspension in a viscous fluid drastically change the character of the flow between the solid walls. The closed form of expressions for the mean film pressure and load carrying capacity, frictional force is obtained. Numerical computations show that the performance of the slider bearings is prepared by the uses of lubricants with additives (micropolar fluids) as compared to the lubricants. Further it is observed that the micropolarity parameters l and N increase the pressure, load carrying capacity, frictional force, coefficient of friction and centre of pressure. The effect of porous parameters causes the reduction of pressure and load carrying capacity.
