Resistance and propulsion performance of a twin skeg ship with different rudder angle [PDF]
Scientific ReportsRudder angle will change the flow field, resulting in different loads and interactions on the hull-propeller-rudder, which will affect the resistance and self-propulsion performance of the ship, and this effect will be amplified on the twin skeg ship ...
