LHJ浮选柱流体静力学研究

Investigation on Hydrostatics of LHJ Flotation Column

从两相流的流型入手，分析维持泡沫流流型的条件，揭示维持高含气率泡沫流的决定性因素．通过静力学分析建立的两相泡沫流的压力平衡关系式，揭示出了含气率Φ、吸气室负压Pv、液体流速U_L三者之间的关系,通过可视化实验确定了维持泡沫流流型吸气室的最低负压值和下导管液体的最低流速．

Condition to keep bubble flow pattern is analysised based on two-phases flow pattern.A main factor to keep high holdup bubble flow is shown.Pressure equation is set up by hydrostatics method for bubble flow pattern. Relationship among holdup Φ,negative pressure Pv in suction chamber, fluid velocity UL are presented.
