本研究的目的是对固体输送管道中运行变量（压降、气体通量和固体通量）之间的关系进行预测。这些预测将从包括两个阶段的质量、动量和能量平衡的基本流体动力学模型中产生。将在模型开发中研究流体-流体、粒子-粒子和流体-粒子相互作用的表示，以及边界条件的适当表述。将进行瞬态二维气固流动的计算机模拟，并用各种可用的实验数据对该模型进行广泛测试。研究结果有助于改进气动系统的设计和操作。

The goal of this research is to make predictions for the relationship among the operating variables (pressure drop, gas flux, and solid flux) in solid transfer lines. These predictions will be generated from fundamental hydrodynamic models comprising mass, momentum, and energy balances for the two phases. Representation of fluid-fluid, particle-particle, and fluid-particle interactions will be investigated in the model development, as well as proper formulation of boundary conditions. Computer simulation of transient two-dimensional gas-solids flow will be preformed, and the model will be extensively tested with a full range of available experimental data. The results from lead to improved design and operation of pneumatic systems.
