Abstract

This paper assesses cavitation inception on an 8.5 m tidal turbine blade by varying design parameters such as pitch angle, rotor speed, and tidal inflow speed. The research method uses JavaFoil to calculate hydrofoil data and AeroDyn to investigate cavitation and performance characteristics of the blade. It was found that two types of cavitation are observed in this blade: tip cavitation and cloud cavitation. To avoid these types of cavitation, the degree of freedom of the pitch angle must be limited to below 8 degrees. It was also found that stall regulated control is more suitable than the pitch-regulation in avoiding both types of cavitation.
