A Simulation Method For The Breaking WavesGenerated By A Submerged Hydrofoil (original) (raw)

This paper presents numerical computations of the flow generated by a submerged hydrofoil in motion below a free surface, based on the two-dimensional Navier-Stokes and continuity equations solved by a finite-difference method based on a modified k-z turbulence model with nonlinear free-surface boundary condition. The breaking process is simulated by the application of a pressure distribution on the free surface when the slope reaches a critical value. The implemented direct simulation including the turbulence provides an accurate representation of the horizontal wave profiles for the free-surface flow around a NACA 0012 wing section.
