Аннотация

The structure of a submerged vertically ascending round bubbly jet is numerically simulated by using the Eulerian approach. The influence of the concentration and diameter of air bubbles on the averaged parameters and fluctuating characteristics of the submerged turbulent two-phase jet is analyzed An increase in the concentration and size of gas bubbles leads to jet expansion (by 35% as compared to the one-phase jet), which testifies to intensification of turbulent mixing with the ambient space. Addition of air bubbles enhances the flow turbulence (by 20% as compared to the one-phase jet).
