Abstract

This article aims to analyze and discuss the presentation of the HS film between two conducting LR elliptical plates. The surface of bearing characterized by stochastic averaging model is assumed to be rough (longitudinally). The stochastically average type equation of Reynolds is solved with the boundary conditions concerned in order to obtain the characteristics of the bearing performance like pressure distribution and load-carrying capacity. The results establish that LR is more helpful as compared to transverse roughness. The calculated results are presented graphically and from this presentation it is clearly seen that the hydromagnetic lubrication substantially maximizes the load of the system of bearing. In addition, the LCC is maximized in the case of (−ve) skewed roughness due to increased plates conductivity and standard deviation associated with the Longitudinally Roughness. Moreover, in the case of (−ve) skewed roughness and (−ve) variance, the adverse effect of variance (+ve), positive skewness and aspect ratio of the plates can be compensated to some extent by the appropriate combination of conductivity and magnetization. Thus, this study makes it clear that longitudinal roughness must be given due respect while preparing the bearing systems.
