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.
