A method is suggested for simulating axisymmetric laminar or turbulent flows formed during the motion of a vortex-ring bunch of given geometry and circulation toward a plane screen. Earlier, similar problems were simulated with the numerical solution

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 nois

The urgency of the problem of jet noise reduction has been rising again at the present stage of aircraft technology development. The main reasons are the following. The studies of attenuation of turbo-machine noise have demonstrated that the jet is o

The approach to the control of aerodynamic and acoustical characteristics of subsonic turbulent jets by means of weak acoustical disturbances was demonstrated in Chap. 2 and 3. In the present chapter we consider some results of experimental study for

The present chapter considers well-known approaches to mathematical simulation of subsonic turbulent jets under periodical harmonic excitation. Particular emphasis is placed on the description (in the framework of these approaches) of generation and

The role of coherent structures in jets and mixing layers becomes deciding between aerodynamic and acoustical characteristics of jet flows. This is true for amplification of acoustical feedback in realization of different kinds of resonance. The simp

A supersonic anisobaric turbulent jet is a complex gas-dynamic object and is characterized by strong spatial heterogeneity of the velocity and pressure fields that are dictated by the presence of the shock system and shear layers with large velocity

The changes in averaged and pulsation aerodynamic characteristics of jets under acoustical excitation should be accompanied by the corresponding changes in the jet natural acoustical characteristics determined by the flow aerodynamic parameters (cf.
