초록
The main objective of the present study is to elucidate a correlation between ship resistances from computational fluid dynamics (CFD)and brake horse powers (BHP) from towing tank in container carriers. The tests were conducted for a range of combinations of trimconditions and speeds. To achieve this goal, 295 cases of numerical simulation have been performed using Star-CCM+ which hadbeen statistically verified to predict ship resistances (Lee & Lee, 2014). Based on the normal distribution of resistance errors in all casesof the 4 container carriers, the confidence interval of numerical error was estimated as [-2.33%,+2.42%] with 95% confidence. Thecorrelation coefficients between the ship resistances of CFD and the brake horse powers of the experiments were higher than 0.93. Asa result, the numerical calculation of ship resistances is able to be utilized in order to provide a quick guidance in selection of theoptimum loading condition.
