Information Support of Optimization Calculation of Vortex Type Granulation Devices

The paper studies the hydrodynamic conditions of gas flow motion and vortex granulator workspace design optimization. A comprehensive approach for determination of the hydrodynamic characteristics of a vortex gas flow and their visualization is proposed. The mathematical approach, based on Reynolds equations for turbulent flows solution, is presented. The mathematical model of equations solution with the definition of gas flow velocity components in any point on the radius and height of vortex granulator is obtained. The value of gas flow components of velocity, received by the results of analytical solution, and experimental data has a high degree of compliance. There is mutual rejection that numerical value of velocities and overall graphic image of diagrams of components of gas flow velocities have the same character. For rate and radial velocity components of gas flow for the initial conditions and changing set of geometrical and technological conditions does not cause such significant change of quantitative distribution value along the radius and height for angular velocity component gas stream. The obtained results form the basis of original algorithm for calculating of vortex granulator hydrodynamic calculation and its basic dimensions optimization selection.
