Summary on Grant Application Form |
|
Many types of high-speed vehicles (aircraft, trains and cars) suffer from aerodynamic-induced noise caused by a turbulent boundary layer over the skin of the vehicles. This can sometimes be alieviated by altering the fluid flow characteristics which cause the boundary layer or by passive treatment of the panel through which the sound is being transmitted, but problems are still often encountered with low frequency sound transmission. Active Noise Control (ANC) techniques using feedback have previously been shown to give good results for the reduction of low frequency noise.The goal of this project is to explore the feasibility of Active Flow-Induced Noise Control (AFINC) both for single and double partitions. A new formulation for the vibro-acoustic response of a single/double partition excited by airflow will be developed and validated so that both the effects of primary/control excitations are taken into account. The proposed study will analyse in detail both the induced vibration of a panel excited by turbulent boundary layer pressure fluctuations and its subsequent transmission/radiation of sound. The understanding of these two phenomena is critical for the appropriate selection of the control sources, error sensors, cost function, and control architecture that may be effective in achieving good active control.
