Analysis and Numerical Simulation of Entrainment Efficiency in Annular Water-air Self-oscillating Jet Pump

  • 摘要: 提出环形自激振荡水射流概念,使用Realizable k-ε湍流模型对环形射流泵和环形自激振荡射流泵内部流动进行了仿真计算,结果表明:环形自激振荡射流泵提高了10%左右的吸气量;对两种射流泵内部流场进行了稳态计算,分析了面积比与吸气量之间的关系;通过瞬态计算阐述了下喷嘴处水气相间不稳定边界层的周期性运动发展过程。根据稳态和瞬态的模拟计算结果,总结出环形自激振荡射流提高对气体的卷吸效果的原因。这为提高射流泵传能效率,研制新型环形自激振荡水气射流泵奠定了理论和应用基础。
