AbstractA bubble structure-based drag model developed for the monodispersed system has been extended to simulate bi-dispersed bubbling fluidized beds. Both dense phase and dilute phase are considered to be comprised of two types of particles with different sizes. The derivation of the structure-based drag coefficient for individual particle based on the force equilibrium principle is proved to be independent of the volume fractions(epsilon(si))of particlei.The multi-fluid model in the commercial software Ansys Fluent is employed to evaluate the polydispersed drag model for the segregation of binary gas-particle flows in a bubbling fluidized bed. It is shown that the simulation results predicted by the new structure-based drag model are in reasonable agreement with experimental data with a 6.34% root mean square error (RMSE). The new structure-based model can capture the particle distribution at the top region of the fluidized bed well. The bubble behaviour can also be captured by the new model well.
