Spectral solution of Reynolds film lubrication equation

, 2019
This thesis presents a spectral solution of Reynolds film lubrication equation. A problem with eigenvalues and eigenvectors has been solved, leading to the resolution of a series, suitably truncated at mmax and nmax, which represents, for any value of n ...

Derivation of the Reynolds type equation with memory effects, governing transient flow of lubric [PDF]

, 2004
In this paper we derive the Reynolds type lubrication equation with memory effects for lubrication of a rotating shaft. Starting from the nonstationary Stokes equations and using the asymptotic expansion we obtain a law that is nonlocal in time and gives

Efficient finite element simulation of full-system elastohydrodynamic lubrication problems [PDF]

, 2012
This thesis is concerned with the efficient numerical solution of problems of elastohydrodynamic lubrication (EHL). Our approach is to consider fully-coupled models in which the governing equations for the lubricating film, the elastic deformation and ...
