Turbulent Flow Modification With Thermoacoustic Waves for Separation Control

Abstract

The objective of the proposed three-year study is to examine the effectiveness of high intensity acoustic waves emitted from a thermoacoustic actuator for active separation control of flow over a wall-mounted hump. A novel graphene-membrane based thermoacoustic actuator is considered as the source of acoustic waves. Carbon based materials have high conductivity which allows for extremely high power efficiency for sound generation. Furthermore, such membrane only requires alternating current to be applied, making it attractive from the point of view of implementation since the actuator can be surface-compliant with minimal weight additions.
