Experimental and Numerical Investigation of Novel Acoustic Liners and Their Design for Aero-Engine Applications

This paper presents a combined experimental and numerical investigation on a novel liner concept for enhanced low-frequency and broadband acoustic attenuation. In particular, two different realizations, derived from conventional Helmholtz resonators (HR) and plate resonators (PR) are investigated, w...
