液体薄膜流稳定性和破断特性的研究进展

Review on flow stability and breakdown of thin liquid films

液体薄膜流的流动稳定性和破断特性直接关系到其高传热传质特性在传统工业和高技术领域的应用。从理论建模和实验研究两方面介绍了近年来在等温、蒸发或冷凝状态下的液膜稳定性特征、破断机理和干斑稳定性及不同因素的影响规律方面取得的研究成果,以及从实验所得准则关系式的一致性和相异性,指出了目前研究中的主要方法和存在的问题,并对其可深入研究的方向和应用前景做了展望。

The researches on the stability characteristics of isothermal, evaporating or condensing film, breakdown mechanism, dry patch stability and effects of different factors are introduced based on theoretical modeling and experimentalinvestigation. The consistency and difference ofempirical correlations ofbreakdown, main methods, problems and prospects are discussed.
