Asymptotic and numerical solutions for shielding of noise sources by coaxial jets
Asymptotic and numerical solutions for shielding of noise sources by coaxial jets
We consider the problem of the shielding of noise by coaxial heated jets, for installation
effect applications. Numerical and asymptotic models are derived, and the validity of these
models in various parameter regimes is discussed. It is shown that cone of silence shielding
can be modeled by the diffraction around a solid body. Comparisons between models and
experiments are shown, and the theories are found to agree well with experiment.

Abstract
We consider the problem of the shielding of noise by coaxial heated jets, for installation
effect applications. Numerical and asymptotic models are derived, and the validity of these
models in various parameter regimes is discussed. It is shown that cone of silence shielding
can be modeled by the diffraction around a solid body. Comparisons between models and
experiments are shown, and the theories are found to agree well with experiment.
