Abstract
The wave resistance of single hull ships with or without bulbous bows was calculated with the improved Noblesse's slender ship theory in conjunction with the technique of elementary-wave-steepness restriction theory.Optimization of the shape parameters of bulbous bows was then carried out using a genetic algorithm.Then the wave resistance reduction of twin bulbous bows was considered.The results show that,within a given range of speeds,high-speed ship DV8 with twin-bulbous-bows experience somewhat reduced wave resistance,the maximum up to 38.5%.
