선외기 부상판이 장착된 선박의 유체성능 검증을 위한 전산유체해석 연구
Computational Fluid Analysis to Verify the Fluid Performance of Vessel Equipped with the Outboard Floating Plate
When operating at high speed on a vessel, a high-speed planing hull occurs nonlinear movements such as stern trim and large sprays. This phenomenon results in the hindrance of stability, embarkation and mission performance. Excessive stern trim during the slides decreases propulsion efficiency and visibility of helmsman due to porpoising and changing the attack angle of the fluid flowing into the propeller. To improve these problems, an outboard floating plate is installed on the cavitation plate to greatly suppress or eliminate the porpoising phenomenon. In this study, to analyze the performance of the floating plate mounted on the outboard engine, numerical analysis was carried out to investigate the resistance applied to the floating plate and the lift generated according to the change of the angle of attack and the flow velocity. The reliability of the floating plate mounted on the outboard engine was verified by applying the floating plate according to the speed and the angle of attack.
