MHD with Viscosity Variation and Velocity Slip between Rough Porous Conical Bearings using Couple Stress Fluid

Abstract

In this study, the effect of velocity slip with viscosity variation using MHD couple stress fluid between rough porous conical bearings is analysed. The modified Reynolds equation is solved with appropriate boundary conditions in dimensionless form to find the pressure distribution which is then used to obtain the expression for load carrying capacity paving the way for the calculation of response time. Numerical computations of the results shows that the MHD on the conical bearings indicate that the slip velocity enhances the pressure distribution and the load carrying capacity of the conical bearings. Also, the effect of roughness parameter is to increase(decrease) the load carrying capacity and the response time for azimuthal (radial) roughness.
