Abstract

The recently developed Reynolds mass flux (RMF) model is applied to simulate the reactive flow in a gas-particle bubbling fluidized bed (BFB). By using this model, the profiles of species/particles concentration and phase velocities are able to be predicted. The proposed model avoids the generalized Boussinesq's postulation, thereby realizing the simulation of anisotropic mass transfer. The simulations are validated by experiments for ozone decomposition in a gas-particle bubbling fluidized bed and satisfactory agreement is found between them. Furthermore, the proposed model successfully characterizes the anisotropy of turbulent mass diffusivity in gas-particle BFB.
