Decrease in the noise of a subsonic turbulent jet ejected from a ring nozzle with longitudinal slots

Abstract

The results of investigations of the aerodynamic and acoustic characteristics of a jet ejected from a ring nozzle with longitudinal slots are presented. It is shown that these slots markedly influence the jet mixing and substantially decrease the jet noise generated in a wide frequency range.
