摘要

The propeller boss cap fins (PBCF) is well known to be one of the most successful energy-saving devices for ships. More than 3,300 sets have been sold since its first introduction in 1987.In this paper, SPIV measurements and CFD computations were carried out in order to investigate the reasons for the difference in the energy saving effects of PBCF in model test and in full scale data. It was confirmed to evaluate the full scale energy saving effect of PBCF by taking into account the propeller inflow in the real ship. As these results, it was suggested that EFD and CFD analysis using simulated full scale ship wake is effective to estimate the energy saving effect of PBCF in full scale. And the effect of energy saving was confirmed to increase in combination with PBCF and other ESD. Also, it was confirmed that the effectiveness of the combination of PBCF and other ESD for EEDI improvement. Furthermore, it was confirmed that PBCF is an effective device to reduce the underwater radiation noise from the cavitation test.
