Abstract

A huge tsunami attack with run-up may cause scattering of containers, which can be a danger for navigating ships. Although some of hydraulic experiments and numerical simulations to track drifting containers in a tsunami attack have been executed previously, not plural floating bodies but a single one was treated in previous studies. In this study, a numerical simulation to predict drifting behavior and submerged area of containers driven by tsunami is carried out. Containers are driven by the fluid force based on the Morison's formula in which the drag coefficients are assumed with taking their rectangle shape into account. Local velocity field is calculated by the nonlinear long wave theory.
