Numerical Modelling of Jenkins Model Based Ferrofluid Lubricated Double Layered Porous Rough Inclined Slider Bearing with Effect of Slip Velocity

Abstract

This article discusses the ferrofluid lubrication of a double layered porous rough inclined slider bearing with the consideration of slip velocity. The ferrofluid flow model of Jenkins is found to be used here. For the development of Reynolds’s equation, the stochastic averaging of Christensen and Tonder for roughness and Beavers and Joseph slip model are factored in to the derivation. The results confirm that the Jenkins model based magnetic fluid flow introduces a better positive effect as compared to Neuringer - Rosensweig model. The adverse effect of transverse roughness can be countered effectively by the Ferrofluid lubrication when the slip is less and this positive effect advances due to the double layered. Lastly, it is seen that some amount of load is always supported even in the absence of flow which is rarely found in the case of traditional lubrication.
