NUMERICAL AND EXPERIMENTAL STUDY ON DRIFT DUE TO TSUNAMI CON SIDERING THE DRAG COEFFICIENT AS A FUNCTION OF CURRENT ANGLE

摘要：

In order to predict the behavior of floating body under tsunami flood appropriately, numerical simulation is effective to reproduce the dynamics with drift. As analyzing the movement of flotsam, it is significant to evaluate the drag force exerted on the float shape. This paper shows experimental results of container’s drag force coefficient as a function of every current angle. And we report the application of a drift simulation method considering the drag force by comparing the drift motion from the experiment in a 2-dimensional plane water tank with that of the simulation result for above-mentioned float model.
