This paper conducts wave-making simulations for hydrofoils running at high speeds. The analysis is performed by constructing the wave-making Green's function due to a two-dimensional vortex filament by means of Fourier transform method. We adopt the developed Green’s function as the kernel function, and approach the problem using the boundary element method. The Green’s function is numerically computed by switching between three expansion forms, namely, Taylor expansion, continued fraction expansion, and asymptotic expansion, depending on the case.
Simulation calculations are performed on the lift force and wave-making resistance acting on the hydrofoil, the generated wave profile, the flow velocity vectors and the pressure distribution around the hydrofoil with a NACA airfoil. As a result, we gained concrete findings for the dependencies of wave-making phenomena upon the wing shape, running speed, submerged depth, angle of attack and other factors.
