Viscosity variation with velocity slip effect using couple stress fluid between rough conical bearings

Year: 2025

Type: article

Abstract: Viscosity variation and velocity slip in porous rough conical bearings with couple stress fluid is investigated. The analytical derivation of the modified Reynolds equations that account for pressure-dependent viscosity is derivedusing a stochastic random variablewith non-zero mean, variance, and skewness. This study numerically examined the impact of couple stress fluid, viscosity variation and slip velocity for pressure, load carrying capacity and time leading to significant improvements in bearings characteristics when roughness effects and slip velocity are present. It was concluded that fluids with micro-structure additives are significantly apparent and the inclusion of couple stress fluid effects enhance the lubrication performance.
