Computational Aeroacoustics: Recent Progress and current challenges


Prof. Sanjiva K. Lele

Dept. of Aeronautics and Astronautics, Stanford University


Abstract

Computational Aeroacoustics is a field where computational approaches are exploited to study aeroacoustic problems, i. e. problems involving aerodynamic generation of sound, and its interaction with flows, structures and wave-bearing media. The talk will begin with a brief survey of aeroacoustic problems arising in applications related to aviation, and the unique computational challenges they present.

The bulk of the talk will illustrate some recent advances in computing the aerodyamic noise. Examples from jet noise including jet screech, boundary layer noise, cavity noise and trailing-edge noise will be shown. We will end with a discussion of current challenges requiring further research.
