## Aeroacoustics

Solving the compressible Navier-Stokes equations means that acoustic waves are included
in the solution (*if the resolution is fine enough and if the accuracy of the numerical
scheme is high enough to be able to be able to represent the high-frequency low-amplitude
acoustic perturbations*). This implies that one can study sound generated by the flow itself -
a branch of Computational Fluid Dynamics (CFD) often referred to as Computational Aeroacoustics (CAA).
