论文摘要
了解复杂的集中泥浆的流动行为对于工业废物管理至关重要。在这项研究中，通过混合多相模型与颗粒流的动力学理论结合的混合物多相模型模拟了水平管道中三相油砂的运输。固体颗粒和沥青液滴是通过工业规模管道内的湍流方案中的非牛顿载体流体传达的。仿真结果显示与现场数据具有非凡的一致性，速度分布的误差<3.5％，压降的误差<15％。对广泛的流量条件进行了系统的参数研究，表明大多数沥青液滴位于管道的顶部区域。我们的发现可能有助于设计一个有效的过程，以在管道运输过程中分离沥青残基。
Understanding the flow behavior of complex concentrated slurries is of tremendous importance for industrial waste management. In this study, the transport of three-phase oil sands tailings in a horizontal pipeline is simulated via the mixture multiphase model coupled with the kinetic theory of granular flow. The solid particles and bitumen droplets are conveyed via a non-Newtonian carrier fluid in a turbulent regime inside an industrial-scale pipeline. The simulation results showed exceptional agreement with the field data, with errors of <3.5% for velocity distribution and <15% for the pressure drop. A systematic parametric investigation was performed for a wide range of flow conditions, showing that the majority of bitumen droplets reside at the top region of the pipe. Our findings may help design an effective process for the separation of bitumen residues during pipeline transport.
