标题： Dynamics of noncohesive confined granular media

摘要： 尽管颗粒物质的普遍性和技术及科学重要性，与分子流体和固体相比，我们的理解仍然非常有限。 直到今天，还没有统一的描述，这似乎遥不可及。 然而，有人提出，通过将流体动力学与相场建模相结合，并采用适当的序参数，可以对非粘性、类似硬球的系统取得重要进展（Aranson和Tsimring，2006）。 在这里，我们回顾了受限颗粒物质的动力学，这种方法已被证明是有效的。 受Olafsen和Urbach（1998）开创性工作的启发，已经进行了许多实验、理论和数值研究，这些研究揭示了各种基本现象。 在本综述中，我们关注其中几个基本方面，即相共存、有效表面张力以及液态的详细描述。 显示英文摘要

摘要： Despite the ubiquitousness and technological and scientific importance of granular matter, our understanding is still very poor compared to molecular fluids and solids. Until today, there is no unified description, which indeed seems unreachable. However, it has been proposed that important advances could be attained for noncohesive, hard-sphere like systems, by combining fluid dynamics with phase-field modeling through an appropriate order parameter (Aranson and Tsimring, 2006). Here, we present a review of the dynamics of confined granular matter, for which this systematic approach has proven its value. Motivated by the pioneering work of Olafsen and Urbach (1998), many experimental, theoretical and numerical studies of model confined granular systems have been realized, which have unveiled a very large variety of fundamental phenomena. In this review, we focus on few of these fundamental aspects, namely phase coexistence, effective surface tension, and a detailed description of the liquid state.
