Title: Disturbance convection velocity in turbulent jets under aeroacoustic excitation.
Authors: Pimshtein, V. G.
Abstract: The velocity of propagation of toroidal and oblique vortices formed in subsonic and supersonic turbulent jets under longitudinal internal and transverse external excitation by finite-amplitude saw-tooth acoustic waves is studied experimentally. It is demonstrated that the convection velocity of vortices is not constant, and the character of its variation depends on the vortex shape.
