【Abstract】 The movement of small particles in a vortex flow is simulated by lattice Boltzmann method.The vortex flow is produced by a flow in a cave,and the trajectory,velocity and anglular velocity of the particles are evalnated with the hydrodynamic force calculated by the momentum-exchange and stress-integration,respectively.At last,multiple particles with different radii moving in a vortex flow are also simulated with the hydrodynamic force calculated by stress-integration.更多还原
