| Abstract: | This paper presents an application of vortex generator on a Multi-Purpose Vessel to reduce the vibration.The test and CFD research are performed,also the trial test results are shown.The 1st and 2nd blade order of pressure fluctuation are reduced by 20%~30% and 50% respectively from the model test.The trial test results show that the vibration on the ship is reduced by 20%~60% at different measured points. |
