Magnetic Fluid Lubrication Of A Double Layered Porous Squeeze Film In Longitudinally Rough Truncated Conical Plates Considering Slip Velocity

In this paper investigation we analyze the impact of slip velocity for a double layered porous magnetic squeeze film in longitudinally rough truncated conical plates. The stochastic modeling of Christensen-Tonder has been invoked for the effect of surface roughness Nuringer-Rosenwing model takes care of magnetic fluid flow while Beavers-Joseph slip model is employed. The graphical results are presented after solving the associated stochastically averaged Reynolds type equation. It is noticed that the magnetic fluid lubrication causes a relatively better performance. Besides, the longitudinal roughness also helps to overcome the effect of slip velocity up to certain extent. However, for any type of improved performance smaller values of porosity and slip velocity are required. The magnetic fluid lubrication results in faster response of the squeeze action. The positive effect of doublelayered in conjunction with magnetic fluid lubrication presents a better picture.
