Abstract

稠密颗粒液体两相流是自然环境与工业生产中广泛存在的一类复杂流动，如滑坡、泥石流等，深入研究稠密颗粒液体混合流的流动特性具有重要的科学意义与工程价值。在颗粒液体两相流的相关研究中，最关键的问题是建立颗粒相的本构方程。近年来，学者们对于两相流中颗粒间相互作用以及颗粒相应力的描述取得了较大进展[1]，但仍未形成统一的认识。在本文中，我们基于斜槽流动装置以及“透明土”技术开展了一系列实验，研究稠密颗粒液体混合物流动的内部特征[2]。利用这些实验数据，在动理学理论框架上，本文提出了一个改进的颗粒相摩擦-碰撞封闭应力模型。然后，通过在OpenFOAM平台上实现这一改进的动理学模型，开发了一个用于模拟两相稠密颗粒流的 Euler 求解器，并通过若干例子测试了本求解器对两相稠密颗粒流流动的适用性。
