Description of the three-phase contact line expansion

EPJ Web of Conferences, 2014
Knowledge of bubble-particle interaction is important in many industrial processes such as in flotation. While the collision (first interaction sub-process) between bubbles and particles is influenced only by hydrodynamic forces, the bubble behaviour ...

An Adhesive Wear Model for Gears in Mixed Elastohydrodynamic Lubrication

Lubricants
In this study, an adhesive wear model for a gear drive in mixed elastohydrodynamic lubrication (EHL) is proposed. The mixed-EHL model combines the average Reynolds equation with the ZMC rough-surface contact model to determine the asperity contact ...

Three-phase contact line and line tension of electrolyte solutions in contact with charged substrates [PDF]

Journal of Physics: Condensed Matter, 2016
The three-phase contact line formed by the intersection of a liquid-vapor interface of an electrolyte solution with a charged planar substrate is studied in terms of classical density functional theory applied to a lattice model. The influence of the substrate charge density and of the ionic strength of the solution on the intrinsic structure of the ...

A Unified Transient EHL-Based Framework for Determining Contact Stiffness and Damping for Application in Spur Gear Dynamics

Lubricants
Time-varying mesh stiffness (TVMS) is a primary contributor to gear noise, vibration and harshness (NVH). Accurate implementation of the lubrication effect on the TVMS is often neglected.

Experimental investigation on the effect of accelerating motion of contact line on the dynamic contact angle

Nihon Kikai Gakkai ronbunshu, 2014
The dynamic contact angle, the angle between the surfaces of the liquid and the solid at a moving contact line, is one of the primary conditions for the dynamics of the liquid surface confined by solid wall.
