Finite element simulation of airflow in a field cleaner

Abstract

Abstract The work is devoted to the study of the dynamics of the grain mass in a stripping field installation and a stationary installation for separating grain. At the first stage, a model of the air mass movement in the installation under consideration is constructed and, on the basis of a mathematical model that takes into account the turbulence of the air mass movement, using the finite volume method in the ANSYS package, the velocity and pressure field is calculated. The influence of the technological parameters of the installations on these fields is studied: the diameters and rotation speed of the stripping drum and the additional drum-fan, the shape of the surface of the upper deck of the installation chamber. The calculations performed allow us to choose rational geometric and kinematic parameters at which no stagnant zones arise in the chamber.
