Abstract

The present study is concerned with the numerical simulation of free-surface waves and wave induced separation in the presence of an intrusion. The results of several simulations are reported. The first study was performed for a NACA0024 surface piercing hydrofoil over a range of several Froude numbers (0.19, 0.37, 0.55), along with wave breaking at Fr=1.0 The NACA0024 foil was of particular interest, as it almost has no separation at large depths; thus the effect of the free surface wave and the wave induced separation could be studied. Free- surface waves and wave induced separation results were evaluated and compared with both the available experimental data and the previous numerical results. The wave breaking flow was also successfully simulated and results were presented. The second series of simulations were carried out for a circular cylinder in order to investigate the shape effects on the wave-induced separation. Results suggest that, at high Froude numbers, the free-surface waves are a function of Froude and not the shape of a body. Flow features with regard to separation, free-surface elevations and drag coefficients were also studied.
