Capillary Water Behavior During Evaporation of Granular Media

Abstract

Intense studies on evaporation in fluid systems have been conducted over the past decades, mainly on sessile droplets which are the simplest bodies to simulate. In this thesis, the evaporation process of a water bridge between two spherical grains is studied. A multi-physics approach is adopted focusing on the evaporation dynamics, the flow motion in liquid, the pressure distribution inside the water bridge, and the vapor behavior combined with the movement of free interface.
