Which risk increases when a submerged hydrofoil experiences increased fluid velocity?

💡 Explanation

Increased fluid velocity promotes instabilities; therefore promoting a turbulent boundary layer. The adverse pressure gradient causes flow reversal and flow separation. This occurs because momentum diffusion exceeds convection within the boundary layer, rather than a suppression of it.
