Modelling of Moving Contact Lines in Two-Phase Flows - DiVA po…

NettetIn 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, Nettet1. mar. 2024 · Contact-line mobility characterizes how fast a liquid can wet or unwet a solid support by relating the contact angle Δ Δ 𝛼 to the contact-line speed U C L. … choline ocd https://cfloren.com

NettetIn this paper, a multiscale moving contact line (MMCL) theory is presented and employed to simulate liquid droplet spreading and capillary motion. The proposed MMCL theory combines a coarse-grained adhesive contact model with a fluid interface membrane theory, so that it can couple molecular scale adhesive interaction and surface tension …
