비대선박에서 구상선수의 길이와 저항성분들과의 상관관계 분석을 위한 수치해석

Abstract

The bulbous bow has long been used in reducing the wave making resistance by varying the velocity field near the bow of the ship. The bulb attenuates the bow wave, thereby reducing the total wave making resistance. Studies have shown that effective positioning of the bulb and its length has a probability of reducing the viscous resistance also. In this paper, resistance calculation of five forms of bulbous bow has been done to find the effect of the bulb length on the resistance of large full form ship. Five bulbs were designed the length, and theoretical resistance calculation has been carried out for these bulbs by CFD code. A comparative analysis of calculated results has been made to find out the relationship between the length of bulbous bow and resistance components for large full form ship.
