Research of Dynamic Processes of Working Medium Movement in a Vibrating Bunker

Abstract

The article presents the results of the study of the regularities of the formation of the circulating vortex motion of the working medium and the behavior of the vibrating hopper body under conditions of symmetric shock-impulse loading. It was established that such loads cause slow circulating motion of the medium, the intensity of which increases with the asymmetric nature of the impacts. This motion has the form of a ring or arc-shaped vortex, covering the entire volume of the working medium. For the analysis of vortex processes, it is advisable to use the integral form of the law of conservation of momentum within the control volume. It is shown that the average circulation speed depends on the impact force, the initial velocity of the vibrating hopper and the mass of the working medium, and the angular velocity of the vortex motion is proportional to the average circulation speed.
