SIMULATION OF A SUBSONIC ISOTHERMAL TURBULENT SUBMERGED JET FLOWING FROM AN ANNULAR NOZZLE
K. N. Volkov UDC 532.529 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.
