Abstract
In this study, experiments were conducted on the effects of a container drifted by wind, wind-driven current and wave of a wind-wave channel. The channel is 28.5 m in length, 1.3 m in height and 1.5 m in width. The wind blown into the channel drives the wind-driven current and wave. In the case that the blower operated at 300 rpm, the kinematic eddy viscosity KZ was measured as 3.46 cm2/s at the fetch x=18 m and 0.475 m above the water surface.
The container model is 1/20 scale of 40 feet container. At the middle of the channel, the container model is floated on the surface of the water and is stilled at its initial position by a rigid steel base. The container model is forced by wind-drag, wind-wave and drag of the wind-driven current. The drag force and force of wind driven current acted on the container model were estimated by calculation in balance of the forces. The result is compared to the drag force coefficient and coefficient of force of wind driven current proposed by the previous researches.
