초록
In this study, the self-propulsion tests are performed in INHA towing tank. And the effective wake characteristics of the KVLCC2 andthe KCS models are compared by the experimental results. The form factor is independent of Reynolds number. To estimate thehydrodynamic performance of a full scale ship, the form factor is determined to consider attendant on Reynolds number. In thisresearch, the power predictions are carried out considering the form factor difference of model and full scale ship. The results of thisresearch could be used as one of the fundamental data to the powering performance prediction.
