Abstract

On the basis of the results of measurements and numerical modeling, the interaction of turbulent jets (swirling and without swirling) with the surrounding environment is analyzed. It is shown that the mechanism of the effect of the jet on the surrounding environment is associated with a decrease in the static pressure in the jet. The nature of the influx of the external medium into the jet is independent of the mechanism of the appearance of reduced pressure, and the kinetic energy of the jet is an energy source for the induced flow.
