Abstract
Investigating turbomachinery noise sources using phased array microphones and beamforming methodologies is becoming standard practice. Methods are available to investigate axial flow turbomachinery, but no methods for centrifugal turbomachinery have been published. The reason behind this is twofold. First, it requires an acoustically transparent yet hydrodynamically sealed window to see into the test rig, which contains many walls and complicated passages. Second, it requires a beamforming method that can organize and process the data collected from the rotating sources. This investigation presents a few of the first steps taken toward developing such a measurement methodology.
