摘要：
The flow of a bidisperse granular material in a vertical cylindrical bunker with a cone discharger is numerically simulated. It is shown that the flow of the fraction of small particles shows different behaviors depending on the size of particles and their weight fraction in the granular material. It is found that there exists a boundary layer in which the flow velocity of the fraction of small particles exceeds its bulk flow velocity. It is also found that the flow velocity of large particles is higher in the presence of the fraction of small particles.
