3D Wave Simulation Basing on VOF Method and Dynamic Grid Technology

In order to investigate 3-D situation, the wind and the waves on the interaction on the influence of water object characteristics, this article through to the second development software Fluent, numerical simulation for 3D wave the dynamic process of the wave. First of all a three dimensional two phase numerical pool, the definition made wave plate boundary for movement, according to the characteristics of sine wave launch made wave plate movement rules, and through the user-defined function (UDF) DEFINE_CG_MOTION macro, realize the made the movement of wave plate, analyzes the cycle 2 s stroke 3 m and cycle 6.0 s stroke 0.5 m of sine wave. Second, blowing and horizontal plane Angle 45 ° 2.0 m/s wind, get the jump irregular wave wave process. The results found that reduce the maximum wind trough value, at the same time, improve the big wave peak, adding to the pool of wave, for numerical simulation of 3-d situation seas over deck, leak, prevent oil spill and the foundation animals.
