概要
- 論文の詳細を見る
A new kind of bulb called stern-end-bulb is developed, which is equipped at the after end of the waterline of ships. Its effectiveness for fine high-speed ships is demonstrated through experiments with three hull forms, wave resistance is reduced by about 20% and power saving of 6% is attained by newly designed stern-end-bulbs. The computer program for wave resistance estimation based on the formulation of Neumann-Kelvin problem is proved to be useful for the design of stern-end-bulb, provided consideration on the existence of free surface shock waves in the near-field of stern is carefully made.
