Patent TW-384352-B (TW)
Title: Optimization of turbo machinery harmonics
Inventor: PARZYCH DAVID J
IPC: F04D29/66
Filed: 1996-11-13
Granted: 2000-03-11
Abstract: A turbo machine assembly includes a number of circumferentially spaced rotor blades, a number V of circumferentially spaced guide vanes axially adjacent to the rotor blades, an annular chamber surrounding the rotor blades, and an intake and exhaust for receiving and discharging air that passes through the annular chamber. When the turbo machine is in operation, spinning mode tones are generated by the interaction of the rotor and guide vanes. These tones are minimized by selecting a number of vanes relative to the number of blades so that selected tones propagate axial to the intake and exhaust of the turbo machine. A sound absorptive material is then positioned so that the tones impinge upon it. Moreover, a tuned duct is positioned in the path of the remaining tones. The turning vanes, placed within the tuned duct, cancel the remaining tones travelling through the duct.
