A method for computational simulation of capillary forces acting between dispersive components’ particles connected with liquid “bridge” has been developed. The method considers dimensions and shape of particles, distance between them, a type of their “contact”, volume and shape of liquid “bridge”, surface tension of liquid, and wetting angle. The offered method is based on good correlation between computational and experimental values of capillary forces. Investigations in capillary interaction between variously shaped particles-sphere, cone and plane - have been conducted. Computational simulation has resulted in ascertainment of basic parameters of particles and of liquid “bridge” exerting appreciable influence on capillary force and capillary pressure values. A conclusion has been drawn that the developed model enables to qualitatively appraise how humidity of air influences equilibrium moisture load in powders.
