摘要：

This paper describes in detail the overall pressure and spectral results in the outer mixing region of three annular jets. The outer mixing region can be considered as the result of the shearing of a single jet by the ambient air. The coherent structures found consist of an array of toroidal jet vortices convecting downstream in the outer mixing region. The structures tend to agree with the ones for a single jet. © 1978, Cambridge University Press. All rights reserved.
