摘要：

In the framework of the two-fluid model, the kinetic theory of cohesive particle flow is applied to bicomponent cohesive particle flow. Based on the Bell particle-particle drag model, the revised Bell particle-particle drag model is presented for the bicomponent cohesive particle flow, considering the impact of the particle surface energy on the collision process. The flow characteristics of a mixture of Geldart group A particles and ultrafine particles were studied. The results show that the simulated elutriation rate is in good agreement with the experimental data, which verifies the effectiveness of the cohesive particles drag model.
