Direct visualization of viscous dissipation and wetting ridge geometry on lubricant-infused surfaces

Communications Physics
Drops are exceptionally mobile on lubricant-infused surfaces, yet they exhibit fundamentally different dynamics than on traditional superhydrophobic surfaces due to the formation of a wetting ridge around the drop.

Solving Wetting Front Dynamics At Pore Scale

, 2010
To understand colloid facilitated pollutant transport in vadose zone, the dynamics of wetting front needs to be understood. Wetting front dynamics is dependent on the contact angle between air-water interface and the soil grain. In this presentation we solve the Navier-Stokes Equations with COMSOL Multiphysics in a pore to develop a relationship ...
