Abstract
Mathematical simulation results for various modes of the steam jet efflux into atmosphere are represented. It is shown that, to describe processes in steam jet, in particular during coherent structure formation, there is a need to use a nonstationary model. Mathematical simulation results for the steam jet efflux into the atmosphere under various modes (subsonic, transonic, and supersonic) are described. Features of the formation and emission of noise by the steam jet are shown in dependence of its parameters at the exhaust line section. The obtained results are qualitatively compared with known experimental data on the location of the acoustical center of the steam jet and for instantaneous velocity field of the underexpanded air jet.
