摘　　要：将采用CFD技术对水平管道中的泥浆输送过程进行数值模拟.分别利用欧拉方法和拉格朗日方法进行计算,得出管道沿程压力分布及损失,并模拟泥浆颗粒在管道内的沉降过程,最后开展实验对数值模拟结果进行验证.结果表明,当输送介质为高质量浓度细颗粒泥浆时,采用欧拉模型模拟更接近实际工况,当管道输送介质为粗颗粒或者沙质土,采用拉格朗日模型更合适.This paper explores how to have a numerical simulation for the slurry transportation process by use of CFD. Euler＇s method and Lagrange method are applied respectively to calculate pipeline pressure distribution and loss. After the simulation of slurry settling process in pipes, its numerical results get verified in the tests. The results showed that when the transmission medium is a high concentration of fine particles of mud, Euler model simulates more closely the actual conditions, when the pipeline medium is coarse or sandy soil, using Lagrange model is more appropriate.
