Coupling Effect of Interfacial Transport on Particle-Surface Capillary Forces

In this investigation, an interest is addressed on getting some fundamental insights on the theoretical analysis of inter-particle forces and interfacial evaporation induced by the existence of liquid at pore level. The imbalance of capillary attractive forces and great potential of heat/mass transport at interfaces are found to be most important in driving the dynamic evolution of the system. Connected by micro liquid layer lying among particle(s) and supporting plate, the particle-surface system can experience both repulsion and attraction interactions. Based on the theoretical model proposed in current investigation, the particle’s mechanical status is found to be closely dependent on particle-surface distance, contact line radius, contact properties and mean curvature of the interface. Meanwhile, geometrical information and governing equations bridge interfacial transport together with possible particle movements.
