Abstract Coagulation is one of the important methods to treat fine particle suspension systems such as slime water. The literature analysis shows that the coagulation process is affected by factors such as hydraulic conditions, suspended particle properties and dosing system. From the perspective analysis of mechanics, these factors can be classified into two aspects : the interaction between particles and the interaction between particles and fluid. The liquid-solid coupling numerical simulation based on these two forces is an intuitive and effective method to analyze the particle aggregation behavior from the mesoscopic scale. In the current mainstream numerical simulation models of liquid-solid coupling condensation process, the CFD-DEM coupling model satisfies most of the simulation studies, and the LBM-DEM is more suitable for dealing with complex flow fields.

Key words： coagulation particles cohesion force hydraulic conditions numerical simulation
