【Abstract】 The two-scale homogeneous method to predict the spatial multi-scale behavior and structure in circulating fluidized bed is proposed based on gas-solid two-phase flow mechanics. The local fluctuations of parameters describing the hydrodynamics of gas-solid flow are predicted by the asymptotic convergence from the macro-scale, meso-sclae to micro-scale. The influence of scale interactions on the flow behavior of gas and particles phases is analyzed.更多还原
