Surface Forces in Particle Technology: Wet Systems

Surface forces in particle technology: Wet systems

Surface forces play a fundamental role in particle processing as they control the stability, adhesion, friction and rheology of particulate systems and information on all of these can be obtained from an analysis of the normal forces measured between particles. Therefore particle processing at all stages can be informed by knowledge of the forces between the constituent particles. For wet parti...

Towards hydrodynamic simulations of wet particle systems

This paper presents the rheology of weakly wetted granular materials in the slow frictional regime, using Discrete Element Method (DEM) simulations. In a split-bottom ring shear cell geometry a slow, quasi-static deformation leads to wide shear bands away from the walls. Dry non-cohesive and cohesive materials are compared in order to understand the effect of liquid bridge capillary forces on t...

Theoretical and experimental study of surface forces in disperse systems

Teoretické a experimentálne štúdium povrchových síl v disperzných systémoch V príspevku sú stručne zhodnotené výsledky priamych experimentálnych meraní povrchových síl medzi makroskopickými povrchmi so zvláštnym dôrazom na tzv. štrukturálny, resp. hydratačno-hydrofóbny typ povrchových síl. Súčasne sú analyzované povrchové sily medzi mikroskopickými časticami modelových disperzných systémov, a t...
