SPH method for two-fluid modeling of particle-fluid fluidization
In this paper a smoothed particle hydrodynamics (SPH) method is proposed for solving the two-fluid model of dense particle-fluid fluidizations. The particle-fluid two-phase flow fields are represented with two types of SPH particles, where the interactions between particles of the same type constitute the inner-phase stress while those between particles of different types result in the drag force. Two typical fluidization systems, namely the liquid-solid sedimentation and single-orifice gas-solid bubbling fluidization, are simulated with this approach, showing good agreement with experimental data.
