The Numerical Simulation Of Solid/liquid Two-phase Flow In The Coal Water Slurry Pump

The coal water slurry pump is the key equipment in the hydraulic transportation piping system. In order to reveal the flow law of solid/liquid two-phase flow with high concentration in the interior system, the article constructed geometrical model of coal water slurry pump by theoretical analysis, numerical simulation in combination with simulation method, based on solid/liquid two-phase hydrodynamics theory. The article applied FLUENT analysis software to numerical simulating and simulation in its interior flow field. On the one hand, it studied the changes and distributing law of solid/liquid concentration, velocity and pressure; on the other hand, it investigated the influence of the different particle concentration and diameters on flow velocity and pressure. It finally obtained the basic flow law of solid/liquid two-phase with high concentration.
