Abstract

In the work, numerical simulations of a turbulent swirling flow in a model tangential chamber were performed. Depending on the swirl number and water flow discharge, various flow regimes are observed: a column vortex, a spiral vortex, a double spiral vortex. In this paper, a study was made of admission air to control the transition between flow regimes. It is shown that when a gas phase is added, a transition from a two-helix structure to a single helical vortex occurs. This phenomenon reproduces the effect observed in the experiment
