    摘要:

    采用文献研究法、理论分析法,分析和研究国内外大颗粒浆体管道输送方面的实验数据和生产实践中的测试数据,通过非线性拟合方法,给出大粒径固体颗粒干涉力修正系数的计算公式。通过分析和研究大颗粒浆体水力坡度(摩阻损失),提出了新的计算模型,并采用相关的试验数据对所提出的浆体水力坡度(摩阻损失)进行了验证,模型的验证表明:提出大颗粒浆体水力坡度计算模型可以为大颗粒浆体阻力损失的研究提供理论依据。

    Abstract:

    The experimental data of large particle slurry pipeline transportation at home and abroad and the test data in production practice was analyzed and studied by literature research method and theoretical analysis method. The equation was given by the nonlinear fitting method for calculating the interference force correction coefficient of large size solid particles,and a new computational model was proposed for hydraulic gradient of large particle slurry based on the momentum transfer relationship between solid particles and water. It was verified by relevant test data for the computational model, and the result showed that the computational model was correct. The research results can provide theoretical basis for the study on the resistance loss of large particle slurry.
