Abstract

Journal of Vibration and Control, Ahead of Print.
Recessed mounting is a common technique for measuring wall pressure fluctuations in turbulent boundary layers. However, cavity resonance can severely distort the measured signal, so correction is required. This study investigates the resonance ...
