- •
Study of vapour cavitation of journal bearing using vibration & acoustic emission.
- •
The vapour bubbles have been captured simultaneously.
- •
The evolution of vapour bubbles during cavitation increases with increase in speed.
- •
There is relative decrease in size of bubbles with elevation of speed.
- •
A band of 175 to 570 kHz frequencies has been reported during cavitation.
- •
The vibration spectrum has peak at a frequency slightly less than 0.5 X.
