Abstract

The penetration of free hollow thin-walled turbulent water jets into water is considered. These jets are generated in a conical jet aerator whose apex angle is 60°. The periods of steady regular self-oscillations appearing during the process of penetration are studied experimentally. A dependence of these periods on the annular nozzle gap width δ, 0.07 ≤ δ ≤ 0.12 cm, is analyzed for the jet discharge range 160 ≤ Q ≤ 550 cm3/s when the height H of the annular nozzle above the water surface belongs to the range 1 ≤ H ≤ 28 cm.
