An analytical framework for evaluating the cohesion effects of coalescence between capillary bridges

Abstract

In this work, we analyse the physical consequences of capillary bridges coalescence between spherical particles agglomerates and more particularly the jump of the capillary force. By referring to Murase et al. (Adv Powder Technol 19(4):349–367, 2008) and Rynhart et al. (Res Lett Inf Math Sci 5:119–127, 2003) about bridges adhered to three particles, we analyse the effects of coalescense between three bridges with two grains and a bridge joining three grains. This monographic synthesis intends to explain analytically and geometrically the significant increase of the inter-particle force, a strengthening cohesion effect, experimentally observed, reported and still largely unelucidated to our knowledge in the literature.
