Recent Advances in Aeroacoustics

Acoustics is one of the oldest examples of applied research, long before the term was even coined: witness the concept of musical scales by the ancient Greeks and the construction of musical and other sound instruments in most civilizations through the ages. Compared with sound in the strict sense of small pressure perturbations in a homogeneous, non-dissipative medium at rest, modern aeroacous...

Computational Aeroacoustics: An Overview

An overview of recent advances in computational aeroacoustics (CAA) is presented. CAA algorithms must not be dispersive and dissipative. It should propagate waves supported by the Euler equations with the correct group velocities. Computation domains are inevitably finite in size. To avoid the reflection of acoustic and other outgoing waves at the boundaries of the computation domain, it is req...

Aeroacoustics on Non-Dedicated Workstations

The simulation of subsonic aeroacoustic problems such as the flow-generated sound of wind instruments is well suited for parallel computing on a cluster of non-dedicated workstations. Simulations are demonstrated which employ 20 non-dedicated Hewlett-Packard workstations (HP9000/715), and achieve comparable performance on this problem as a 64-node CM-5 dedicated supercomputer with vector units....
