Conclusions
-
1.
Aerated water jets are finding wide use in solving a number of practical problems. A determination of the effect of braking of the velocity field in a jet as a function of the air content is especially important.
-
2.
On the basis of laboratory experimentation, a formula (8) of the decrease of the relative axial longitudinal velocities in water-air jets spreading beneath the water level as a function of the air content in their initial section is derived.
-
3.
The length of the initial section of a jet changes considerably in the presence of aeration and can be determined by formula (9).
