| Abstract: | The bulbous bow is widely used in commercial ships .The quantity of the resistance reduction is directly determined by the geometry of the bulbous bow. This paper develops an interpolation method for the bulbous bow geometry, and reduces design parameters of bulbous bow to five. On this basis, this paper then proposes a new design method for bulbous bow by using multi-island genetic algorithm for lines optimization of the bulbous bow with lowest wave-making resistance. A design practice for the bulbous bow for KCS is performed, and it receives a further reduction of wave-making resistance by 10%. |
