Аннотация: <jats:p>The flow with a disperse phase in a tangential vortex chamber at high swirl numbers was studied using a numerical methods. The swirling flow is created using nozzles directed at an angle to the chamber axis. The numerical flow model was based on computational fluid dynamics methods and described the turbulent flow of water.Показать полностьюTurbulence was simulated using the large eddy simulation method. Based on the results of single-phase flow simulation, particle motion was calculated using the Lagrange approach. The results of the single-phase flow simulation are consistent with the data from the corresponding experimental studies. The movement of particles depends significantly on their density. For massless particles, the average residence time of the particles is noticeably lower for a higher swirl number. The residence time of heavy particles is 1.5 - 2 times higher than the similar residence time of massless particles. At the same time, most of the heavy particles do not leave the tangential chamber and are deposited.</jats:p>
