“…The non-Newtonian micropolar fluid impact has a higher load carrying capacity in conical bearings is investigated by Lin et al [12]. Sangeetha and Govindarajan [13] analyzed the effects of viscosity variation and couple stress fluids for circular stepped plates. It is observed that the combined influence of couple stress and magnetic effects are significant.…”

MHD effect using micropolar fluid between rough conical bearings is analyzed in this paper. The Reynolds equation is derived in the form of magnetic field using the Eringen principle with Christensen theory. The stochastic modified Reynolds equation for two types of one-dimensional structure, the radial roughness pattern and azimuthal roughness patterns is derived for micropolar fluid. In terms of dimensionless pressure, load carrying capacity and time, the numerical results are presented. The importance of roughness, MHD and micropolar fluid is greater than that of the classical Newtonian case. From the analysis, the impact of micropolar fluid and electrically conducting fluid increases the load carrying capacity further decreases the time relative to the Newtonian instance. On the whole, the squeezing film characteristics of conical bearings is improved for higher values of coupling number and Hartmann number.

“…The influence of viscosity variation between the circular stepped plates using couple stress fluid is examined by Hanumagowda [8] and found that the pressure and load carrying capacity is enhanced with an increase in viscosity variation parameter. Sangeetha and Govindarajan [9] analyzed the effects of magneto hydrodynamic(mhd) and viscosity variation using couple stress fluid between circular stepped plates. It is observed that the combined influence of couple stress and magnetic effects are significant.…”

The effect of velocity slip with viscosity variation between porous rough circular stepped plates with couple stress fluid is examined. A stochastic random variable having a non-zero mean, variance, and skewness is used to model a more general type of surface roughness equation also the modified Reynolds equation accounting for pressure dependent viscosity is analytically derived. The numerical solution obtained for the non-dimensionless pressure, load carrying capacity and time. It is observed that the impact of roughness and viscosity variation using a couple stress fluid between circular stepped plates has been discussed. These effects improved the ability of load carrying capacity as compared to the corresponding Newtonian case.
