  • In this paper, a local mixing particle-in-cell method isproposed for multiphase flows. The method can be used for dense particleflows. Under the grid of particle parcel scale, which is called as Eulercell in this paper, the total particle volume in the cell is calculateddirectly based on the Lagrangian method. Therefore the particle volumefraction (concentration) on the Euler cell and the fluid control volume canbe obtained accurately. Meanwhile, at new time step, particles on the Eulercell are assumed to be mixing sufficiently and come into being a new parcel.Comparing with the previous methods, the proposed method is more efficientand accurate. For the sedimentation in vertical and inclined vessels, andthe bimodal suspension in a vertical vessel, the numerical results agreewith the experimental results.
