Compared with experimental investigation,numerical simulation has overwhelming advantages in its flexibility and economical efficiency,therefore it becomes an important method to obtain the microscopic mechanisms and the macroscopic effects of fine particle agglomeration subjected to an acoustic field.The relevant study progress and present status were reviewed.The orthokinetic,hydrodynamic and acoustic streaming mechanisms of acoustic agglomeration were introduced,and the numerical simulation methods for acoustic agglomeration such as sectional algorithm,method of moments,and Monte Carlo method,were also presented.It is proposed that based on the coupling of acoustic agglomeration mechanisms,visualization simulation using Multi-Monte Carlo method combined with visual programming technique can be an important development direction for the simulation of acoustic agglomeration.
