A study on the added resistance and wake distribution of a ship in waves using CFD

초록

While increasing interest in eco-friendly Internationally, the IMO (International Maritime Organization, IMO) has in-troduced EEDI(Energy Efficiency Design Index) to regulate greenhouse gas emissions of the ship from 2013. For this reason, efficiency of the vessel operation has become a major concern of shipbuilding and shipping industry. As a study on the efficiency of a ship, reducing of added resistance in waves by decreasing the reflected wave of bow has been activated. Improving the bow shape at the short-wavelength region has been primary study of added resistance. In this study, the added resistance variation according to the change of bow shape is estimated from short-wavelength region to long one. In addition, the possibility of operating performance improvement is examined by studying of the wake distribution on CFD and KVLCC2 without rudder and propeller is conjugated.
