Abstract Solid particles may experience different kinds of cohesive forces, which cause them to form agglomerates and affect their flow in multiphase systems. When such systems are simulated through computational fluid dynamics (CFD) programs, appropriate modelling tools must be included reproduce this feature. In review, these strategies addressed for various scales. After an introduction the forces (van der Waals, electrostatic, liquid bridge etc.), approaches categorized under three methodologies. For diluted slurries very fine particles, many researchers succeeded with pseudo‐single phase approaches, employing a model non‐Newtonian rheology. This was especially popular sludges anaerobic digestions or certain types soils. other cases, continuum‐based seem more adequate, including cohesiveness kinetic theory granular flows restitution coefficient. Geldart‐A experiencing van Waals primary focus studies. Finally, when each particle is modelled as discrete element, force can directly specified; widespread wet fluidization case. general overview main strategies, achievements, limits provided.
