推移质间相互作用力研究

Research on Shear Force in Slurry Flow

沉降性浆体中固体颗粒处于滑跳移运动状态时,固体颗粒将受到摩擦力的影响。推移质的整体摩擦力等于推移质间剪切力和推移质与管壁间摩擦力的和。任意推移质的剪切力与固体颗粒的体积分数成比例,由力的平衡方程可以推导出其比例系数。

When the solid particle was in slipping or jumping motion state in slur ry flow,the solid particle will be influ enced by frictional force.The whole fric tional force is equal to the sum of the shear force and the frictional force.The shear force of the bed load is proporti onal to the volume fraction of the soli d particle,its proportion coefficient ca n be calculated by the balance equation of forces.
