蒸汽在水中的直接接触冷凝(DCC)在许多工业设备中都会发生。对冷凝状态的准确理解和预测是获得适当装置设计的关键。现有的二维流型图能够预测有限流动条件下不同的冷凝流型，但如果考虑不同的喷嘴尺寸，则不能准确地预测流型。本文提出了一种新的三维区域图，并通过实验进行了验证。此外，文中还讨论了采用注汽流型图所需的修正。
Direct contact condensation (DCC) of steam in water occurs in many industrial devices. Crucial to obtain an appropriate design of the device is an accurate understanding and prediction of the condensation regimes. The two-dimensional regime maps presently available are able to predict different condensation regimes for limited flow conditions, but fail to predict regimes accurately if a different injector size is considered. In this paper, a new three-dimensional regime diagram is presented, and validated against experiments. Furthermore, corrections necessary to adopt the regime diagram for steam injection into a water flow are discussed in the paper.
