9530873辛克莱本研究的目的是对固体输送管道中的操作变量(压降、气体、流量和固体流量)之间的关系进行预测。这些预测将从基本的流体动力学模型中产生，该模型包括两个阶段的质量、动量和能量平衡。在模型开发中，将研究流体-流体、颗粒-颗粒和流体-颗粒相互作用的表示，以及边界条件的适当表述。对二维气固两相流动进行了计算机模拟，并用大量的实验数据对模型进行了广泛的检验。由此产生的结果将导致改进气动系统的设计和操作。这是卡内基梅隆大学开始的研究的继续。***

9530873 Sinclair 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 performed, and the model will be extensively tested with a full range of available experimental data. The results from this will lead to improved design and operation of pneumatic systems. This is continuation of the research begun at Carnegie Mellon University. ***
