- Title

- Abstract
The onset of turbulence and formation of large-scale patterns (coherent structures) in subsonic submerged jets are considered from the standpoint of noise-induced nonequilibrium phase transitions of the second kind. It is shown by the example of noise-induced oscillations of a pendulum with a randomly vibrating suspension axis that such a transition can be controlled by an additional harmonic action. The known possibility of notable suppression or intensification of turbulence in jets and free shear layers by means of a slight acoustic action at one or another frequency can be attributable to such control.
