Abstract: Chugging is one of the typical condensation regimes for direct contact condensation,and it has the characteristics of subcooled water periodically entering and leaving the tube.In addition,there exists strong turbulence,heat and masstransferin vapor-liquid interface.The evolution process of condensation vapor-liquid interface in a typical period,pressure oscillation and heat transfer are reviewed and summarized in this paper.The spatio-temporal evolution of chugging was divided into five typical stages:bubble growth,bubble collapse,water suction,internal condensations and steam ejection.As for transient pressure oscillationinacycle,it starts with a negative spike followed by sinusoidal oscillation,and it has the characteristic of high amplitude and low frequency.At present,the research on vapor-liquid interface transien theat transfer is not perfect,whose coefficient is generally obtained by a simplified model.In addition,the latest application of chugging in the field of high-efficiency heat dissipation of electrical components under micro-channel conditions is also briefly reviewed in the forecast part.

Key words: chugging, surface behavior, heat transfer, pressure oscillation

摘要: 间歇凝结由于具有过冷水周期性进入蒸汽管并排出的特点而不同于蒸汽直接接触凝结的其他流型,该过程伴随汽液界面瞬时热质传递和强湍流。文中主要从典型周期内凝结汽液界面演变过程、压力振荡以及热量传递三个方面进行回顾和评述,就间歇凝结的时空演变而言,可大致分为5个典型阶段,即汽泡增长、汽泡破裂、过冷水被吸入蒸汽管、管内凝结以及蒸汽再次喷出。在压力振荡方面,间歇凝结压力瞬变从负峰值开始后进行正弦波动,并具有低频高振幅的特性。目前,关于汽液界面瞬时传热方面的研究仍有较大提升空间,与之相关的界面传热系数大多通过简化模型获得。此外,在展望部分还对微通道条件下间歇凝结在电器元件高效散热领域的最新应用进行了简要评述。
