Paper Title:
CFD Simulation for Displacement Deep-Vee Vessels on Resistance Influence Factor
  Abstract

Resistance influence factors of displacement type Deep-vee forms are analyzed with eight hull forms provided. The free surface viscous flow of these forms is calculated by air-water two phases RANS equations with RNG turbulence model and volume of fraction method. Total resistance, pressure distribution and wave profile of bow are presented. Some results can be taken as follows: while maintaining the same tonnage, L/B ratio and draft, the resistance performance of Deep-Vee vessels is excellent at high speed if a large transverse dead rise angle was located from 50%front midship to 25% backward midship; The resistance performance at a lesser L/B and draft is worse if the displacement and dead rise angle is the same; Furthermore, it can be improved by a cigar-shaped bulbous bow. The change of pressure distribution for cigar-shaped bulbous bow is more slightly than that of tobacco pipe-shaped bulbous bow.
