Stability of Interacting Counter-Swirling Gas Jets in the Furnaces of Fire-Tube Hot-Water

摘要

Simulation of the velocity field of two counter-rotating horizontally rotating jets with precessing vortex cores showed that the velocity in the cross-section at the jets of jet jets changes like a single jet to the middle, and then corresponds to the velocity profile in the interaction of counter-rotating streams, while the velocity field is stratified according to the magnitude of the displacement, which is explained by the change in the region of interaction of the jets. It is revealed that the evolution of the velocity peak caused by the addition of the velocities of interacting jets determines the optimal ratio between the displacement of jets in the horizontal plane and the distance between the points of their outflow equal to 0.25.
