The Coanda effect at a ship

Caption

One of the main sources of aerodynamic drag is the square-shaped back of the ship’s superstructure. The Chalmers researchers have created a superstructure design with convex edges and highly compressed air flowing through “jet slots”. The Coanda effect then allows the air pressure on the ship’s hull to be balanced out which, in turn, considerably reduces aerodynamic drag.
