Industry/University Cooperative Research Activity: Gas-Liquid-Solid Fluidization

研究了气-液-固流态化的基本行为。研究了四个方面：气泡动力学、流变性、探头发展和环空流态化。在气泡动力学中，将结合气泡尾迹和液体流态区之间的固体交换行为来研究气泡及其尾迹的特征。利用高速可视化技术研究了二维流化床中气泡的动力学。对于三相流态化系统，将尝试基于流变性对颗粒进行可能的新分类。建立了用于测量三相流态化床液-固流态区固含率的光纤探头。

Research addressed an investigation of the fundamental behavior of gas-liquid-solid fluidization. Four areas are studied: bubble dynamics; rheological behavior; probe development, and annular fluidzation. In bubble dynamics, the characteristics of bubbles and their wakes will be investigated in conjunction with the behavior of solids exchange between the bubble wake and the liquid-fluidized region. The high speed visualization techniques will be employed to examine the bubble dynamics in a two-dimensional fluidized bed. Possible new classification of particles based on the rheological behavior will be attempted for three-phase fluidized bed systems. The fiber optic probe will be constructed for measurement of the solids holdup in the liquid-solid fluidized region of three-phase fluidized beds.
