Ferrofluid lubrication of circular squeeze film bearings controlled by variable magnetic field with rotations of the discs, porosity and slip velocity [PDF]
Royal Society Open Science, 2017 Based on the Shliomis ferrofluid flow model (SFFM) and continuity equation for the film as well as porous region, modified Reynolds equation for lubrication of circular squeeze film bearings is derived by considering the effects of oblique radially ...

On the reynolds lubrication equation [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 1988 Let Ω be a bounded open set in R 2 with “smooth” boundary ∂Ω. Ω is the region where two solid bodies are in contact. These two solids are moving and the average of their velocities is denoted by V=(V 1 ,V 2 ). The pressure p=p(X) which develops in a fluid layer confined between these two bodies satisfies the so- called Reynolds lubrication equation: (1)

Rigorous justification of the Reynolds equations for gas lubrication [PDF]
Comptes Rendus. Mécanique, 2005 The goal of this Note is to give a rigorous justification of the compressible Reynolds model for gas lubrication, via asymptotic analysis. We start from the equations of motion of compressible viscous fluid in a thin domain and study the limit as the domain thickness tends to zero. At the limit we find the known engineering model.
