Abstract

Based on a numerical solution of the Navier–Stokes equations, simulations of the development of disturbances and transition to turbulence in an isobaric jet exhausting from a round nozzle have been carried out. The eddy-resolving simulations have been carried out in a three-dimensional setup. Simulation results are compared with available experimental data.

期刊介绍： The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
