As international regulations on environmental pollution become stricter, new and existing ships are required to reduce their carbon emissions. Therefore, it is essential to develop a high-performance ship with low carbon emissions. A variety of high-perfor-mance propellers are being developed worldwide to achieve this goal. In this study, the Coanda effect was applied to a two-dimensional hydrofoil for the development of a high-performance propeller. CFD (Computational Fluid Dynamics) was used to compare the lift and drag performance between NACA66(mod.) and Coanda hydrofoils in two dimensions. The pressure distribution of each hydrofoil was compared for the same lift coefficient. The pressure distribution and cavitation performance of the hydrofoil with the Coanda effect were also compared with those of the NACA66(mod.) hydrofoil.
