Abstract
In present paper a three-dimensional Vortex-In-Cell method concerning the two-way coupling is developed for gas-solid flow induced by particles free falling. The vorticity equation is solved by the vortex method, and the gas velocity field is solved by the dual-potential method, while particles are tracked in Lagrangian frame. The simulation of free falling particles and induced air flow demonstrates that the radial velocity of air satisfies Gaussian distribution. It also confirms that the particle flow rate has little influence on the spread of particles, while particle velocity increases with increasing the particle flow rate.
