Adjoint Error Estimation for Elastohydrodynamic Lubrication [PDF]
, 2008 In this thesis, adjoint error estimation techniques are applied to complex elastohydrodynamic lubrication (EHL) problems. A functional is introduced, namely the friction, and justification is provided as to why this quantity, and hence its accuracy, is ...

Physical Review Letters, 2010 Thin fluid films can have surprising behavior depending on the boundary conditions enforced, the energy input and the specific Reynolds number of the fluid motion. Here we study the equations of motion for a thin fluid film with a free boundary and its other interface in contact with a solid wall. Although shear dissipation increases for thinner layers

Approximate Analytical Model for the Squeeze-Film Lubrication of the Human Ankle Joint with Synovial Fluid Filtrated by Articular Cartilage [PDF]
, 2010 The aim of this article is to propose an analytical approximate squeeze-film lubrication model of the human ankle joint for a quick assessment of the synovial pressure field and the load carrying due to the squeeze motion.

Lift force acting on a levitating drop over a moving wall
Nihon Kikai Gakkai ronbunshu, 2015 We experimentally investigate a levitating drop over a moving wall. Between the drop and the wall, a thin air film exists. In this study particular attention is given to examine whether the lift force generated inside the thin air film is dominant force ...

A Potential Field Description for Gravity-Driven Film Flow over Piece-Wise Planar Topography
Fluids, 2019 Models based on a potential field description and corresponding first integral formulation, embodying a reduction of the associated dynamic boundary condition at a free surface to one of a standard Dirichlet-Neumann type, are used to explore the problem ...

Adaptive Numerical Methods for Elastohydrodynamic Lubrication [PDF]
, 2001 Numerical solutions to elastohydrodynamic lubrication problems have been computed for the last half century. Over the past decade multilevel techniques have been successfully applied in several solvers and significant speed-ups achieved.
