振动流化床中流体动力学研究

STUDY ON HYDRODYNAMICS OF VIBRATED FLUIDIZED BEDS

本文比较详细地介绍了振动流化床流体力学的数学模型和空气动力学研究，概述了在振动流化床中数学模型的进展和振动参数与最小流化时的床层压降、最小流化速度、床层空隙率的关系，并且提出了振动流化床流体力学的未来工作的设想。

A mathematical models of dynamics and hydrodynamics in vibrated fluidized beds was presented in this paper. Progress of mathmatical models and relations between the vibrational intensity and the minimum fluidization velocity,Umv, the bed pressure drop,△Pmv, the minimum fluidization velocity,Umv, the porosity of the bed,ε, were described. Some idea about further study in this area were proposed.
