- Numerical simulation for turbulent air flow structures over wind waves
抄録
The characteristics of turbulent air streams over wind waves are analyzed by applying the twoand three-dimensional κ-ε models. Sinusoidal waves and the whitecapping waves that's surface profiles are observed in laboratory experiments are employed as the targets for computing the air streams over them. The air stream over the sinusoidal waves contains a small and weak wake region and weak three-dimensional structures in the computational results. On the other hand, the computed air streams over the observed whitecapping waves contain wakes evidently at the lee side of the waves, and its characteristics strongly dependent on the wave surface profiles. The distributions of computed turbulent energy over the waves are also discussed as the turbulent flow properties of the air streams.
