摘要: The hydrodynamics of fluidization for two thin ''two-dimensional'' fluidized beds, one containing a centrally located rectangular obstacle and the other three square tubes roughly approximating portion bed combustor (FBC), was solved using FLUFIX/MOD2 computer program. monolayer energy dissipation erosion model extended to include solids viscous stress compared with Finnie model. Hydrodynamic convergence studies were performed first bed. Computed rates from compare more favorably both beds available data than those 27 refs., 15 figs.
