本文综述了毛细多孔介质中干燥的微孔尺度模型的最新进展。干燥中孔隙网络模型的发展首先是由干燥的几个基本特征推动的，这些特征不能在连续介质模型的框架内完全解释。这些特征包括干燥斑块现象和恒定干燥速率周期。动力的第二个来源是在多孔介质中不混溶置换的孔隙尺度模拟方面取得的进展，以及人们越来越相信这一领域发展的概念可以用于模拟干燥。回想起这些概念。我们描述了它们如何被用来发展一个由传质驱动的干燥的孔网络模型。本文综述了主要结果，包括花纹的形成、干燥速率以及有关含有二元混合物的多孔介质干燥和换热影响的一些最新结果。讨论了用网络模型计算有效输运性质的方法。讨论了尚待解决的问题。(C)2002 Elsevier Science B.V.保留所有权利。
This paper presents a review of the recent advances in pore-scale modelling of drying in capillary porous media. The development of pore network models in drying has been first motivated by several fundamental features of drying that cannot be fully explained within the framework of continuum models. These features include the dry patch phenomenon and the constant drying rate period. A second source of motivation has been the advances made in pore-scale modelling of immiscible displacements in porous media and the increasing conviction that concepts developed in this area could be utilised to model drying. These concepts are recalled. We describe how they have been used for developing a pore network model of drying driven by mass transfer. A review of the main results is made, including pattern formation, drying rates and some recent results regarding drying of a porous medium containing a binary mixture and the influence of heat transfer. The use of network models for computing effective transport properties is discussed. Open problems are discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
