초록

CFD tools were intensively used to develop a bulk carrier hull form of 180,000 DWT. HCAD and WAVIS were utilized to vary and evaluate the hull forms. LCB and framelines were systematically changed starting from a mothership. Resistance characteristics have been assessed by evaluating the wave-pattern resistance and viscous pressure drag along with the wave profile and wake distribution. It was found that the hull forms obtained from LCB variations were not good enough to satisfy the target resistance coefficient because of large wave generation at the design speed. After choosing the appropriate one from the LCB variation series, bow and stern framelines have been modified to improve wave-making characteristics and wake distribution, respectively. Model tests were performed to confirm the CFD results. Furthermore, the effect of free surface on CFD application was investigated, and a few comments are given on the difference between WAVIS version 1.4 and 2.0.
