双组分冷模射流流化床气化炉内流体动力学特性模拟

The studied insights into the average properties of binary system defined by Goossens et al. are incorporated into an Eulerian-Eulerian Computational Fluid Dynamics (CFD) model for simulating the hydrodynamics in a cold model of jetting fluidized-bed gasifiers. Some of the essential hydrodynamic parameters, including gas- and solid-velocity profiles, time-averaged voidage profiles, and jet penetration height, are investigated in this paper. These results show the CFD approach is an effective tool for predicting hydrodynamics in jetting fluidized beds with multi-component mixture.
