Modeling of the moving deformed triple contact line: influence of the fluid inertia.
For partial wetting, motion of the triple liquid-gas-solid contact line is influenced by heterogeneities of the solid surface. This influence can be strong in the case of inertial (e.g., oscillation) flows where the line can be pinned or move intermittently. A model that takes into account both surface defects and fluid inertia is proposed. The viscous dissipation in the bulk of the fluid is as...
متن کاملObservation of Non-classical Rotational Inertia in Solid Helium - an Indication of Superflow in Solids?
The phenomenon of Non-Classical Rotational Inertia, in which a body does not rotate with its rotating container, has been recently observed in solid Helium-4. This property is shared by superfluid liquid helium. The recent findings might be evidence of superflow in solids. Superfluidity or flow sans dissipation is commonly associated with liquids. Counter-intuitive as it may seem, quantum mecha...
متن کاملClassical rotational inertia of solid 4He.
The observation of reduced rotational inertia in a cell containing solid 4He has been interpreted as evidence for superfluidity of the solid. We propose an alternative explanation: slippage of the solid, due to grain boundary premelting between the solid and dense adsorbed layers at the container wall. We calculate the range of film thickness, and determine the viscosity that will account for t...
متن کاملWave Reflection and Refraction at the Interface of Triclinic and Liquid Medium
A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...
متن کاملVOF simulations of the contact angle dynamics during the drop spreading: standard models and a new wetting force model.
INTRODUCTION In this study,a novel numerical implementation for the adhesion of liquid droplets impacting normally on solid dry surfaces is presented. The advantage of this new approach, compared to the majority of existing models, is that the dynamic contact angle forming during the surface wetting process is not inserted as a boundary condition, but is derived implicitly by the induced fluid ...
