| Abstract: | To optimize the profile for a bulbous bow, experimental measurements were performed with 3 slightly different bulbous bow cases in a low speed wind tunnel. The spatial distributions of surface pressure as well as pressure fluctuations were obtained, and assessments on the bulbous bow cases were made in terms of surface pressure characteristics. The results of this study provided technical support for the design of the bulbous bow profile directly. |

| Keywords: | bulbous bow profile surface pressure pressure coefficient distribution pressure fluctuation wind tunnel test |
