  • Aerodynamic characteristics of an airfoil NACA2410 in flight being close to wavy water surface are investigated numerically. The Reynold average Navier-Stokes(RANS) equation of unsteady incompressible flow, the standard k-ε turbulence model and volume of fluid(VOF) method were solved. Appropriate mesh and time step were used to avoid the distortion of regular cosine wavy surface. The difference of the solid wall of water waves and water surface wave was compared. The results of the solid wall are closer to the cosine curve distribution. The aerodynamic forces of the airfoil are periodic when it flies over cosine-shaped water surface. The variation of the aerodynamic forces in one period is presented. The effect of wavelength and wave amplitude on mean and amplitude values of aerodynamic forces is provided.
