SIMULATION OF A SUBSONIC ISOTHERMAL TURBULENT
SUBMERGED JET FLOWING FROM AN ANNULAR NOZZLE

A simulation of the flow in a jet has been carried out 
with the use of the Reynolds-averaged, space-filtered Navier-Stokes 
equations closed by the k -  model of turbulence 
and the subgrid RNG model of eddy viscosity. The results of calculations 
carried out on the basis of the k -  model 
and the results of simulation of large vortices are in quantitative 
and qualitative agreement with the corresponding measurement data, 
which is evidence in favor of the main laws defining the decay of 
the gas-dynamic behavior of cold-gas submerged jets and the fluctuations 
of their parameters.
