COMBINED IMPACT OF ROUGHNESS AND SLIP VELOCITY ON THE FERROFLUID LUBRICATION OF THE POROUS EXPONENTIAL SLIDER BEARING

An endeavor has been made to analyze the combined impact of roughness and slip velocity on the Ferrofluid lubrication of porous exponential slider bearing. The surface roughness is described in perspective of the stochastic model of the Christensen and Tonder. The magnetic fluid flow is administered by the model of Neuringer-Rosensweig. Beavers-Joseph's slips model represents the impact of slip velocity. The concern stochastically average Reynolds type equation is solved to get the pressure distribution in the bearing system then the load carrying capacity is figured numerically. The outcomes appeared in graphical structures confirm that the magnetization goes to the limited extent to counter the impact of slip velocity and roughness.
