Open full text 13 citations

Abstract

The generation of wave due to moving hydrofoil in steady streams close to a free surface is presented.The potential-based boundary element method is employed to the NACA4412 hydrofoil with linearized dynamic and kinematic boundary conditions on the free surface.The perturbation velocity potential is calculated using the Green formulation and Kutta condition.The numerical results of waves generated by the hydrofoil are presented and discussed at various Froude numbers and immersion depths.
