Notes
Numerical experiments were conducted by means of the k- ε turbulent model to understand the three dimensional turbulent structure of the wind induced flow in the closed water body. First, three types of the k- ε models were evaluated in terms of their adaptabilities to the wind induced flow. Next, the Low Reynolds number k- ε model, which had the best adaptability, was used to analyze the influence of the aquatic plants luxuriating on the water surface. The analysis was performed under the different luxuriant patterns in which the part of water surface in the water tank is covered with the aquatic plants. The analytical results indicated that the scale of the flow became very small below the aquatic plants. In addition, the flow field was divided into two portions when the aquatic plants were located at the center of the water tank. In this luxuriant pattern, the scale of the flow circulation, which was assessed through the distribution of the eddy viscosity coefficient, significantly decreased compared with other patterns although the luxuriant rates of the aquatic plants were equal.
