FORMATION OF BUBBLES BY CAVITATION

Figure 2. Cavitating model propeller. Picture made with a 1/30,000-sec flash. Shows heavy tip vortices extending 

 down over leading edge and fairly wide area of blade covered by burbling cavitation. This is a right-hand propeller and 

 the water is flowing from left to right. 



FiGtTRE 3. Cavitating model propeller. Short sections of the tip vortices are quite clear and the development, growth, 

 progress, and disappearance of individual bubbles in the cavitation on the back of the upper blade can easily be followed. 

 This is a right-hand propeller and the water is flowing from left to right.
