A technique has been developed which allows the effect on the cavitation inception number of the gas content in the water to be predicted in cavitation experiments. The predicted results have been compared with data obtained during experiments to measure cavitation inception in the tip vortex of a low aspect ratio hydrofoil and have shown good agreement.
The results showed that the gas content affected the cavitation inception number significantly at low free stream speeds, particularly below about 4 m/s.
