The article presents the results of the study of the process of moving a particle of a multicomponent mixture in a spiral flow mixer. The kinematics of particle motion in cylindrical coordinates are considered and the influence of design and operating parameters on the trajectory of movement is analyzed. The relevance of the study is due to the need to increase the efficiency of mass transfer processes, ensure uniform distribution of components in heterogeneous systems, and optimize the energy consumption of equipment. A mathematical model of the absolute and relative particle velocity is presented, taking into account rotational and translational motion. Special attention is paid to the influence of the geometry of the working body on the uniformity of mixing and the efficiency of the process. The article analyzes the influence of the geometry of the screw blades (diameter, spiral pitch, width and angle of inclination) on the circulation flows, mixing intensity and uniformity of dispersion of components. The theoretical provisions are confirmed by the data of modern experimental and numerical studies, as well as the results obtained by domestic and foreign scientists. In particular, it is proven that optimization of design parameters allows to significantly reduce the time to achieve homogeneity of the mixture without a significant increase in energy consumption.
The practical significance of the article lies in creating scientific prerequisites for developing methods for designing and modernizing spiral flow mixers, taking into account the specifics of processing various types of multicomponent mixtures. The developed particle motion scheme can be used for mechanical engineering and optimizing spiral mixer designs in the food and processing industries.
The conducted research expands the theoretical understanding of the dynamics of multicomponent mixtures and provides a scientific basis for the rational design of spiral-type mixers with optimized geometric and kinematic parameters. The implementation of the proposed model will allow for more accurate prediction of particle motion trajectories, reduction of dead zones in the working chamber, and enhancement of mixing uniformity.
