Spatial Distribution of the Cavitation Aggressiveness in a High Speed Cavitation Tunnel
Original language description
The cavitation aggressiveness was investigated by means of impact loads measurements. The cavitation impact load spectra were measured using PVDF film sensors placed at different locations in the eroded area of an aluminum disk. A high speed cavitation tunnel was used to generate a cavitating flow near to the sample surface. The eroded area was divided into seven regions and exposed to six cavitation regimes. The data was acquired by a high speed oscilloscope and automatically analyzed to identify the collapses peaks. Peak amplitude and peak count were obtained from the signal analysis. PVDF sensors were calibrated by a ball drop method. Each sensor had an individual calibration constant. The results represent relations between the cumulative peak rates, impact forces, sensor location positions and flow velocities.
