High Frequency Acoustic Suppression - Experimental & Computational Overview

Abstract

The recent history of the relatively new field of high frequency acoustic suppression is outlined. Key experiments actuator developments, and obvious applications are described. Differences between low frequency forcing and high frequency forcing are outlined, and definitions for the two regimes are offered. Preliminary first steps toward numerical simulation of the high frequency acoustic suppression are critiqued and compared to existing experimental evidence. Future research directions are briefly described.
