Influence of Bowshape on Hydrodynamic Performance of
 Mono Wave-Piercing Craft

Abstract

Abstract: Typical wave piercing bows were modeled to study the influence of bowshape on hydrodynamic performance of mono wave-piercing craft. Numerical methods were developed by solving URANS (Unsteady Reynolds Averaged Navier-Stokes) equations and adopting different dynamic mesh methods for this study. Simulations of hulls with different wave-piercing bows running in calm water and waves were conducted. Mono wave-piercing craft with slender wave-piercing bows are not sensitive to bow forms in short waves, and have smaller resistance, hull motions and acceleration than a planning boat. Resistance and wave making in calm water of a mono wave-piercing craft in large scale are not sensitive to bowshape, while bowshape has great influence on resistance, hull motions and wave making in calm water of a mono wave-piercing craft with small scale and high speed.

Key words: wave-piercing bows, mono wave-piercing craft, hydrodynamic performance, hull motions
