Hybrid Atomistic–Continuum Formulationsand the Moving Contact-Line Problem
We present a hybrid atomistic–continuum computational framework for the treatment of dense fluid problems with emphasis on the coupling of molecular dynamics with continuum (finite element/spectral) methods for problems involving multi-fluid dynamics in the presence of multi-fluid interfaces. The technique is an extension of the single-fluid framework already presented by the author. The well-k...
متن کاملNot even Hercules : the moving contact line problem
The problem of the moving contact line is described and the singularity that arises after application of the classic hydrodynamic model is discussed. The central experimental observation that the motion is rolling is confirmed by a simple experiment. Subsequently, some of the various methods that have been developed to resolve the difficulty are briefly described. In addition, the lubrication e...
متن کاملMoving contact line of a volatile fluid.
Interfacial flows close to a moving contact line are inherently multiscale. The shape of the interface and the flow at meso- and macroscopic scales inherit an apparent interface slope and a regularization length, both named after Voinov, from the microscopic inner region. Here, we solve the inner problem associated with the contact line motion for a volatile fluid at equilibrium with its vapor....
متن کاملSolvability condition for the moving contact line.
We consider the motion of a contact line between a fluid, gas, and solid, as it occurs when a drop advances over a solid surface. This motion is controlled by a microscopic length scale near the contact line, such as a slip length or the precursor thickness. The capillary profile inside the drop is linked to the contact line through an intermediate region which is characterized by an interface ...
متن کاملMoving contact line with balanced stress singularities
A difficulty in the classical hydrodynamic analysis of moving contact-line problems, associated with the no-slip wall boundary condition resulting in an unbalanced divergence of the viscous stresses, is reexamined with a smoothed, finite-width interface model. The analysis in the sharp-interface limit shows that the singularity of the viscous stress can be balanced by another singularity of the...
