- Title
THE NEW STERN DESIGN - A SOLUTION OF DRAG REDUCTION OF SHIPS.
- Authors
Ali, B.; Bejan, M.
- Abstract
The paper presents an original stern shape design. It leads to a better fluid flow, which reduces the drag. There are presented the direct and reverse problems and the numerical implementation. A current tube is taken into consideration. It contains the propeller, extends towards the prow and includes the entire stern section of a classic hull. The dynamics of a propeller depends on environment system. The fluid flow around a propeller working on a ship is different to that one tested in free water or in a cavitation tunnel. The fluid flow near the stern is a key factor for the ship design. The consequence is that a new stern design is a solution of drag reduction of ships.
