Introduction for amazing (cavitation) bubbles

Although the word ‘cavitation’ was originally coined by R. E. Froude and first cited by Barnaby and Thornycroft in 1895, the phenomenon was conjectured much earlier by L. Euler in his theory of water turbines in 1754. However, actual cavitation was first discovered and investigated by Barnaby and Parsons in 1893 when they found that the formation of vapour bubbles on the propeller blades was responsible for the sea-trial failure in 1885 of a British high-speed warship HMS Daring. In 1895, Parsons established the first water tunnel for cavitation study and discovered the relationship between cavitation and the damage to the propeller. It was Rayleigh who, in 1917, laid the theoretical foundation for cavitation study by solving the problem of the collapse of an empty cavity in a large mass of liquid
