摘要：
The numerical simulation of the pulp motion in direct pipe has been held on the basis of the developed mathematical model of motion for the mixture of liquid and solid particles using the lattice Boltzmann equations. The model was verified by the original experimental data on the hydraulic resistance coefficients at the pulp motion in pipe at outlet from disintegrator. The dependences of the hydraulic resistance coefficient on the concentration ratio of water and solid particles including highly saturated suspensions have been obtained. The intrinsic velocity profiles for the motion of suspensions with various Reynolds numbers have been determined.
