NUMERICAL SIMULATION OF THE PROCESS OF AERODYNAMIC SEPARATION OF FINE-GRAINED BULK MATERIAL

Various methods can be used to numerically simulate the aerodynamic separation of fine-grained bulk material, including discrete element methods, finite and bounded domain methods. In all these equations are solved numerically, results determine trajectories velocities air particles. The Discrete Element Method (DEM), on basis which study will conducted, is designed for modeling granular flow materials. purpose research movement loose material under influence calculate parameters its in Simcenter STAR-CCM+ software package. following were selected as physical models: gas, two-dimensional, separated flow, gradients, ideal isothermal fluid energy equation, unsteady implicit, turbulent, Reynolds averaging Navier-Stokes K-Epsilon turbulence model, admissible two-layer K-Epsilon, wall distance, double layer any y+, gravity, Lagrangian multiphase, DEM multiphase interaction. As a result numerical simulation package, distribution their components area separator was constructed. adopted factors: diameter particles liquid fraction impurities d, particle supply speed f, v. Based processing obtained data set Wolfram Cloud patterns changes position intersection line two fractions (distance x) content δ zone from factors established. presented detailed method other
