An exact analytical solution for the second order slip-corrected Reynolds lubrication equation [PDF]

open access: yesFME Transactions, 2015
We derive a general slip-corrected compressible Reynolds lubrication equation, valid for any choice of the slip velocities, and show that it possesses the exact analytical solution.

Effects of elastic ball and coating on pure squeeze EHL motion for constant load with couple stresses using FDM method

open access: yesMATEC Web of Conferences, 2017
In this paper, an elastic sphere approaching a lubricated elastic coating surface with couple stress lubricant is explored under constant load condition. The finite difference method (FDM), Gaussian elimination, and Gauss-Seidel iteration method are used

Hydrodynamic modelling of hydrostatic magnesium extrusion [PDF]

open access: yes, 2006
Wilson’s hydrodynamic model of the hydrostatic extrusion process is extended to meet the geometry found on residual billets. The transition from inlet\ud to work zone of the process is not considered sharp as in the model of Wilson but as a rounded edge,

Numerical analysis of Reynolds equation for gas lubrication at a high .LAMBDA. region.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986
In this paper, a new scheme is presented for solving the Reynolds equation for gas lubrication at a high Λregion by the direct numerical solution method. This scheme derives from the concept that Poiseuille flow has an elliptical property and Couette flow has a parabolic one.
