Theoretical Modeling with Validation of a Combined HQ-Liner System for Turbofan Engine Noise Control
The combination of traditional passive acoustic liners with Herschel-Quincke (HQ) waveguides is proposed in this work as a device for Turbofan Engine Noise Control. The approach consists of installing circumferential arrays of HQ tubes on the lined sector of the inlet of a turbofan engine. A theoret...
