Particle-particle drag is one of the most important influencing factors of the fluid dynamic behavior in a bubbling fluidized bed. Based on an Euler-Euler gas-solid two phase model, a particle-particle drag model considering particle slope coefficient of segregation is presented for simulation of the bubbling fluidized bed with two different sizes particles and a uniform gas inlet. Comparing the simulating results with Owoyemi's experimental and numerical results, it can be seen that the particle-particle drag model, considering the particle slope coefficient of segregation, can well predict and analyze the characteristics of particle segregation in the bubbling bed.
