Abstract
Cavitation is a dynamic phenomenon occurring in fluid flows, where the local static pressure is lower than the saturated vapor pressure at working temperature. The growth and collapse of cavitation bubbles leads to corrosion and pitting of metal surfaces. Considering the fact that erosion by cavitation is still one of the current problems, it is important to detect the initiation, fully developed point of cavitation and to analyze its characteristics. In this research, an attempt is made to study acoustic waveform of cavitation in the globe valve. The waveform is transformed by Fast Fourier Transform and its important parameters such as amplitude, energy, frequency and so on are analyzed.
