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

点击翻译按钮获取中文摘要

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.
