摘要

摘要: 为定量研究冰浆清洗过程中冰浆的体积分布和壁面剪切力分布，并探索最优工艺参数，研究结合颗粒流动力学理论（KTGF），使用欧拉-欧拉方法和剪切应力传输模型（SST）建立了计算流体力学（CFD）模型，并利用文献实验数据验证了模型的流动特性。在完成常见工况下125组不同参数的冰浆冲洗过程模拟后，优化评价指标并得出了最佳冲洗工艺参数。结果表明：初始浓度高的冰浆能对管壁上下都进行有效清洗，浓度为60%冰浆有效剪切力占比为77.39%。颗粒直径较大的冰浆表现出明显的上浮行为，固体颗粒分布的不均匀性随颗粒直径增大而增大。流速是影响冰浆对壁面剪切力的最重要因素，累计剪切力随流速增加而增大，且分布更加均匀；流速为1.0 m/s时有效剪切力占比为83.16%。当冰浆初始浓度为50%，粒径为0.5 mm，冲洗速度为1.0 m/s时，累计剪切力均值为11.59 Pa·s，此时冲洗效果最佳。该研究可为冰浆清洗供水管道作业提供理论指导。

Abstract: To quantitatively investigate the volume distribution of ice slurry and the distribution of wall shear forces during the ice slurry pigging process， and explore the optimal process parameters， this study integrated the kinetic theory of granular flows （KTGF）， adopted the Euler-Euler method and the shear stress transport （SST） model to establish a computational fluid dynamics （CFD） model. The flow characteristics of the established model were verified using experimental data from relevant literature. After simulating 125 sets of different parameters for the ice slurry pigging process under common working conditions， the evaluation indicators were optimized， and the optimal flushing process parameters were determined. The results indicate that ice slurry with a high initial concentration can effectively clean both the upper and lower parts of the pipe wall， with the effective shear stress ratio of 60% concentration ice slurry reaching 77.39%. Ice slurry with larger particles exhibits significant upward movement behavior， and the non-uniformity of solid particle distribution increases with the increase in particle diameter. Flow velocity is the most critical factor affecting the shear stress exerted by ice slurry on the pipe wall； the cumulative shear stress increases and becomes more uniform with the increase in flow velocity， and the effective shear stress ratio at a flow velocity of 1.0 m/s is 83.16%. When the initial concentration of ice slurry is 50%， the particle size is 0.5 mm， and the flushing speed is 1.0 m/s， the average cumulative shear stress is 11.59 Pa·s， achieving the optimal flushing effect. This study can provide theoretical guidance for the operation of ice slurry pigging in water supply pipelines.
