TopicDevelopment of innovative methods of investigation of noise generation mechanisms by turbulent flows
The main results are: (i) Creation of the new anechoic facility which enables turbulent jet and vortex ring noise investigation; (ii) Development of azimuthal decomposition technique (ADT) for measurements by means of reduced number of microphones adapted to open rig; (iii) application of noise source localization technique (beamforming) to real aircraft engine; (iv) Development of methods for measurement and analysis of sound field modal structure in the engine inlet; (v) Development of liner impedance eduction methods for the engine ducts and methods of liner manufacturing.
