Numerical Simulating for the Cyclone Separator Equipping with Acoustic Agglomeration of Inhalable Particulates

In this paper, the numerical simulation method was used to simulate the inhalable particles movement under the action of acoustic force. The flow and particle trajectories in the cyclone separator were simulated detailed by two-phase models, in which the acoustic agglomeration of particle was considered using the acoustic agglomeration dynamics equation and kernel function. The collection efficiency of the cyclone separator was discussed. It is shown that the collected efficiency has a 6% increase by aerosol agglomeration effect. The simulation results are worth to optimization design of the inhalable particle separation device.
