Inertia and Couple-Stress Effects in a Curvilinear Thrust Hydrostatic Bearing

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
The flow of a couple-stress lubricant in a clearance of a curvilinear thrust hydrostatic bearing with impermeable walls is considered. The flow in the bearing clearance is considered with inertia forces.
