RUDDER, PROPELLER AND HULL INTERACTION BY RANS

One of the most important tasks in the shipping industry is the education of the ship officers and improvement of the maneuverability of the ships, that is why the requirements applicable to these activities play the critical role in the increasing of the safety at sea. In turn, this has increased the industry interest in numerical simulators considered a very strong tool to be used during the investigation of the ship's maneuverability and also for training purposes.

As a result, stronger requirements have been established concerning the reliability of the maneuvering models on which the mechanisms of the simulator is based on, as well as to their accuracy and overall technical quality. The simulators have proven effective, but it shall be noted that there are several areas where some additional knowledge would be appreciated and useful for improvement of the models.

And one of such areas would be the interaction between the ship's rudder, her propeller and hull, playing a top role in successful modeling of the ship's maneuvering. The present document is fully devoted to this problem and its content will be interesting for the people dealing with scientific investigations and researches in this area.
