According to the method of the computational fluid dynamics (CFD), the effects on the filling pipeline resistance of some factors, like the slurry volume concentration, the flow rate, the pipe diameter, the solid mixture density and others, are evaluated, 360 groups of the pipeline resistance loss values are obtained; Using the least squares and linear regression method, the parameters in the transportation resistance model are calculated. With four common operating points selected, an error analysis of the calculation model is made, and according to the method of the regression coefficient significance test, the degree of the influence on the pipeline resistance loss of each factor is obtained finally. The error of the calculation model results against those of the pumping experiment with loop is around 5%, so it could meet the needs of the engineering design and can be used to reduce the pipe resistance., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null,

articleAbstract=为准确计算某矿山高浓度超细全尾砂充填料浆管道输送阻力损失，在固-液两相流理论的基础上，综合全尾砂充填料浆管道输送阻力影响因素，通过因次分析法构建高浓度超细全尾砂充填料浆管道输送阻力模型。运用计算流体动力学方法（CFD）研究充填料浆体积浓度、流速、管道直径、固体混合料密度等因素对管道输送阻力的影响，得到360 组管道阻力损失值；采用最小二乘法回归计算管道输送阻力模型系数，并抽取4 组常用工况点对计算模型进行误差分析，根据回归系数显著性检验方法，得到各因素的影响程度关系。计算模型结果与泵送环管实验的误差在5%左右，能满足本矿山充填系统设计需要。, correspAuthors=null,
