선박 측면 파공에서의 기름 유출 방지를 위해 설계된 앵커형 봉쇄장치의 유동해석

초록

As international regulations on environmental pollution intensify, existing and new ships need to reduce their carbon emissions. Therefore, it is essential to develop a high-performance, low-carbon emission ship. A variety of high-performance propellers are being developed worldwide as one of the directions for the development of high-performance, low-carbon emission ship. In this study, it was focused that coanda effect was applied to two-dimensional hydrofoil for the development of high performance propeller. And, CFD was used to compare the lift and drag performances between NACA66 and coanda hydrofoils in two-dimension. the pressure distribution of each hydrofoil was compared at the same lift coefficient. Also, the pressure distribution and cavitation performance of the hydrofoil with the coanda effect were compared with those of the NACA66 hydrofoil.
