Measuring the Effects of Transverse Grooves on the Top Camber of a Hydrofoil

Measuring the Effects of Transverse Grooves Applied to the Top Camber of a Hydrofoil

It is hypothesized that continuous 2cm transverse grooves to the top camber of a hydrofoil will increase lift yield. It is believed that the grooves will create an area of cavitations across the top camber, and reducing the pressure on the top camber of the foil.

Hydrofoils are used throughout the maritime industry to reduce drag of vessels by lifting the hull out of the water with airfoil-like structures submerged beneath the boat. Transverse grooves are applied to airfoil wings to reduce drag of the wing as it cuts through the air, and it is believed that the same cavitations which reduce drag could increase lift on hydrofoils.
