We describe a mechanical/acoustic study of a short-ducted axial flow fan. The purpose is to compare mechanical noise to that caused by flow phenomena.The eigenfrequencies of the fan are identified through measurement and finite element computations. The ...

At moderate Reynolds numbers and angles of attack, the Laminar Boundary Layer (LBL) becomes unstable on the surface of airfoils, and causes periodic vortex shedding, which means undesired tonal peaks in the spectrum of the emitted aeroacoustic noise alon...

This paper summarizes a case study example on the methodology used for phased array microphone measurements in a realistic acoustic environment. A ducted fan rotor is measured in an environment, where structure born noise and aerodynamically generated no...
