Coherent-Phase Monitoring of Cavitation in Turbomachines


Cavitation is the process of boiling fluid which occurs when local fluid dynamic pressures in the areas of accelerated flow drop below the vapor pressure of the local fluid. The principle for cavitation detection is based on a unique phenomenon associated with cavitation physics, i.e., when cavitation occurs in a rotating system, the periodic rotational components (such as RPM and its harmonics) will amplitude modulate the wide-band high fequency noise generated from the collapse of cavitation bubbles. Such a Wide-Band Modulation (WBM) phenomenon (a narrow-band discrete signal multiplied by wide-band random noise) will generate hidden periodicity in a monitored dynamic response signal thus providing a unique signature in the high frequency region conducive to cavitation detection. 8.5" X 11"
