Haiek Y. Substantiation of the parameters of the process of cleaning the air flow by the rotating cyclone of mobile grain separators

The dissertation solves a scientific problem of efficiency improvement of the cleaning process for the dusty air stream in the aspiration systems of mobile grain separators, which is implemented by stage cleaning with intermediate removal of dispersed particles by using the developed rotational cyclone with a multi-disk after-cleaner. Mathematical modeling of the dusty air stream cleaning process, based on the dynamics of a heterogeneous medium with the properties of viscous liquids, was carried out. Mathematical models of the dynamics of a two-phase medium of dusty air flow in the working areas of the developed rotational cyclone were developed. The influence of structural and technological parameters of the developed rotational cyclone and the properties of dusty air flow were taken into account at the models development stage.
