摘　　要：根据两相流流型转换理论,推导出了气泡泵从弹状流向泡状流转变和从弹状流向块状流转变时液体流量、气体流量与管径的关系式;根据空气提升理论、能量平衡、质量平衡推导出了气泡泵的性能关系式。根据上述关系式,具体分析了爱因斯坦制冷循环工况下气泡泵的性能,分析结果表明,在弹状流下限、大的沉浸比时液体循环量较大。Based on the theory of two phase flow regime, a model was developed to analyze the relation between flow rate and diameter under the conditions of transition from slug flow to bubble flow or chum flow. Based on the theory of air lift, energy balance and mass balance, a formula for the bubble pump performance was presented. Bubble pump tube diameter, submergence ratio, heat power, gas flow rate and liquid flow rate were varied to analyze the Einstein refrigeration system performance; results indicate that liquid flow rate increases with increase in submergence ratio on low limit of slug flow regime.
