Effect of Slip Velocity on a Magnetic Fluid Based Squeeze Film in Rotating Transversely Rough Curved Porous Circular Plates

Abstract

This paper studies the effect of slip velocity on a magnetic fluid based squeeze film in rotating rough curved porous circular plates. The studied surfaces are assumed to be transversely rough. The surface of the upper curved plate is calculated using an exponential function and towards the lower curve plate along the surface administered by a secant function. The slip model created by Beavers-Joseph has been used to evaluate the impact of slip velocity. The roughness is designed using the stochastic method of Christensen and Tonder. The results of the related Reynolds type equation are used to determine the pressure distribution after which the final load carrying capacity is calculated. The results confirm the fact that the bearing system displays a better performance as opposed to the traditional fluid based bearing system. The roughness has a staunch impact on the bearing system. For ensuring a better performance, it is suggested that the slip parameter must be set at the minimum level.
