Model propellers cavitation test (Same shapes as adopted in the ship)

Normal blade angle(Blade angle for open-waters), at a speed of 9 kt

What is a propeller cavitation test?
A test in which a propeller is rotated in a circulating water tank simulating the actual fluid field to observe the occurrence of cavitation phenomena and to estimate its adverse effects. The observation and measurement can help predict propeller damage and improve propeller shape.
