Characterisation of sheet cavity noise of a hydrofoil using the Ffowcs Williams–Hawkings acoustic analogy

•Sheet cavitation noise on a hydrofoil is predicted to be of monopole nature.•Radiated noise is shown to correlate with second temporal derivative of total cavitation volume and load fluctuations.•High frequency noise may not be predicted without modifications to the cavity model. Concerns about pol...
