Abstract

Analysis was conducted to predict the influence of tube size on two‐phase flow regimes for flow condensing in mini/micro tubes. According to the importance of the interfacial tension compared to the interfacial stress, the regimes were classified into three kinds: axial symmetrical, semisymmetrical, and asymmetrical. The results indicated that the surface tension of the fluid media obviously affects the flow regimes; for tubes with an inner diameter less than 100 to 600 mm, the flow regimes would be axially symmetrical depending on the media. © 2002 Wiley Periodicals, Inc.
