Abstract: Computational aeroacoustics (CAA) is an important research area which connects aerodynamics and acoustics. This research area involves simulations of flow-induced acoustic noise and can be broadly categorized into three different methodologies based on the approach used for estimating acoustic field. First two methodologies use computed fluid flow information to further calculate acoustic field details using either an acoustic analogy approach or by solving set of perturbation equations.

The acoustic spectrum of axial flow machines
S.E. Wright
- 01 Apr 1975
TL;DR: In this paper, the authors compared rotor spectra from a variety of axial flow machines and acoustic trends examined, and found that the minimum broad band noise generated by ducted and free field rotors corresponds to laminar and turbulent boundary layer shedding.

Response of the shear layers separating from a circular cylinder to small-amplitude rotational oscillations
TL;DR: In this article, the frequency response of the shear layers separating from a circular cylinder subject to small-amplitude rotational oscillations has been investigated experimentally in water for the Reynolds number (Re) range 250 to 1200.
Aeroacoustic Computation of Cylinder Wake Flow.
Jay C. Hardin,Stanley L. Lamkin +1 more
TL;DR: In this article, the sound radiation is obtained by integrating over the flow field with the Coriolis acceleration as the source term and a low frequency Green's function technique, and time histories, spectra, and directivity of the radiated sound are obtained.

Yan Bao,Dai Zhou,Yao-Jun Zhao +2 more
TL;DR: In this article, a two-step Taylor-characteristic-based Galerkin method is developed based on the introduction of multi-step temporal Taylor series expansion up to second order along the characteristic of the momentum equation.
