本文讨论了当前传热学界在预测微通道内两相流流型方面所面临的挑战。这些挑战包括缺乏通用术语，国际研究界对流动模式分类的要求以及由于流动模式的视觉分类而产生的主观性。提出了气泡流、段塞流、搅动流和环状流的通用流型分类方法。最后，一个数据库，包括超过1500个数据点的一系列流体被用来评估目前的非绝热流型过渡模型的成功，并了解的重要参数，导致流型过渡。
A discussion on the current challenges that face the heat transfer community in predicting two-phase flow patterns in microchannels is presented in this paper. These challenges include lack of universal terminology, a requirement for an agreed flow pattern categorisation by the international research community and subjectivity due to visual categorisations of flow patterns. The generic flow pattern categorisation of bubble, slug, churn and annular flows are suggested to alleviate these problems. Finally, a data bank consisting of over 1500 data points for a range of fluids was used to assess the success of current diabatic flow pattern transition models and to understand the important parameters that cause flow patterns to transition.
