The effects of density on subsonic jet noise
Abstract
The noise of impulsively started jets of mixtures of helium and argon ranging from pure helium to pure argon is compared with available data on the noise of hot air jets. It is concluded that there is strong evidence that the noise of subsonic jets in the rear arc depends on velocity and density only, and that the noise is independent of the way in which the density is achieved, whether by heating an air jet or by mixing cold light gases.
