Ship hydrodynamics and environment


This project aims at improving the environmental impact of shipping.
Almost all freight which is transported between continents is still
transported by ship. This has an impact on the environment because of
fuel usage, leading to pollution and heating upon the atmosphere.
Moreover, ships produce noise. Noise is a sign of energy loss, but noise
is also affecting passengers and the environment. One noise source is by
cavitation near a ship screw.

The project consists of two subprojects.

Subproject 1 (air lubrication) aims at improving the efficiency of ship
transport by using air bubble lubrication, and studies the behavior of
the water-air surface numerically to improve the understanding of the
physics responsible for the escape of air from the air cavity.

Subproject 2 (sound production) studies the production of sound at a
cavitation cavity, like produced by a ship screw, and aims at the
development of numerical modeling that can faithfully reproduce this sound.
