Calculation of the movement of polydisperse mixtures of solid particles in the flow of a Newtonian fluid in a horizontal pipe

摘要

The influence of pressure force; weight; the Archimedes, Magnus, and Safman forces; turbophoresis; and hydrodynamic resistance on solid particles, as well as impact interactions between particles and the lack of space of liquid flux in the interparticle region was taken into account during the motion of polymodal two-phase flow. The distribution of the volume concentration of solid particles was defined by their diffusion process and the motion velocity in transverse direction under the influence of the listed forces. The considered computation method showed satisfactory agreement with experimental data on the distribution of solid phase concentration and average velocity of suspension carrying flux.
