VERTICAL LOW-HEAD JET IN A TRANSVERSE FLOW

The action of a turbulent flow on an injected normally 
low-head axisymmetric jet has been investigated experimentally. Empirical 
dependences describing the geometry of the jet axis in a transverse 
air flow have been obtained. It has been shown that the maximum temperature 
and velocity curves do not coincide; the thermal axis lies lower than 
the dynamic axis. The expressions obtained describe a change in the 
axial values of the velocity and the temperature in the direction 
of propagation of the jet. It has been shown that the attenuation 
of dimensionless axial parameters in the jet carried away by the transverse 
flow is more rapid than that in the case of a submerged jet and a 
wake.
