Not even Hercules : the moving contact line problem
نویسنده
چکیده
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 equation for thin films is derived for the linear slip-shear boundary condition and Van Der Waal force potential that depends on the height of the thin film. This associated partial differential equation serves as the starting point for many numerical and analytical studies of the moving contact line problem.

Molecular Hydrodynamics of the Moving Contact Line in Two-Phase Immiscible Flows
The no-slip boundary condition, i.e., zero fluid velocity relative to the solid at the fluid-solid interface, has been very successful in describing many macroscopic flows. A problem of principle arises when the no-slip boundary condition is used to model the hydrodynamics of immiscible-fluid displacement in the vicinity of the moving contact line, where the interface separating two immiscible ...
متن کاملA variational approach to moving contact line hydrodynamics
In immiscible two-phase flows, the contact line denotes the intersection of the fluid– fluid interface with the solid wall. When one fluid displaces the other, the contact line moves along the wall. A classical problem in continuum hydrodynamics is the incompatibility between the moving contact line and the no-slip boundary condition, as the latter leads to a non-integrable singularity. The rec...
متن کاملThe Sharp Interface Limit of a Phase Field Model for Moving Contact Line Problem
Abstract. Using method of matched asymptotic expansions, we derive the sharp interface limit for the diffusive interface model with the generalized Navier boundary condition recently proposed by Qian, Wang and Sheng in [9, 11] for the moving contact line problem. We show that the leading order problem satisfies a boundary value problem for a coupled Hale-Shaw and Navier-Stokes equations with th...
متن کاملOn the moving contact line singularity: asymptotics of a diffuse-interface model.
The behaviour of a solid-liquid-gas system near the three-phase contact line is considered using a diffuse-interface model with no-slip at the solid and where the fluid phase is specified by a continuous density field. Relaxation of the classical approach of a sharp liquid-gas interface and careful examination of the asymptotic behaviour as the contact line is approached is shown to resolve the...
