Verification of the Results of Numerical and Mathematical Modeling of Two-Phase Flow in a Continuous-Action Pneumatic Mixer

In this study, the motion of a two-phase flow with particles of different shapes is simulated using numerical methods in the SolidWorks Simulation program. In the course of the study, the parameters of the average velocities of the carrier medium and particles in the flow at the inlet and outlet of the mixing chamber were established. The identity of the equations of the mathematical model of the vortex motion of a two-phase flow inside the mixing chamber of a pneumatic mixer with the trajectories and velocities of a two-phase flow simulated in the SolidWorks Simulation program is confirmed. The results of numerical modeling of the average absolute velocities of a two-phase flow in a mixing chamber are presented, which reflect the kinematic parameters for the carrier medium and particles at the inlet and outlet of the mixing chamber. The verification of the mathematical model of the vortex motion of a two-phase flow with the results of numerical modeling of a two-phase flow in a pneumatic mixer using the SolidWorks Simulation calculation complex is carried out. It has been established that the discrepancy between numerical and mathematical (analytical) modeling methods does not exceed 8.55% for the carrier medium and 5.70% for particles of different shapes. The obtained research results can be used as the main approach to verifying technological processes in equipment that can be calculated using both analytical (mathematical) and numerical methods.
