Abstract
In the case of multiple arrangement of cylindrical tanks, tsunami flow pattern becomes different from the case of a single tank by the interaction between tanks. Therefore, wave forces of tsunami on cylindrical tanks depend on the arrangement pattern and the distance between tanks. In this study, 3D-CFD has been carried out for tsunami flow around multiple arrangement of cylindrical tanks. The applicability of 3D-CFD has been verified by the comparison between the calculation result of 3D-CFD and the experimental result of Sakakiyama1). In addition, characteristics of tsunami flow pattern and wave pressure has been investigated from the calculation result of 3D-CFD and the experimental result of Sakakiyama1). The knowledge of multiple arrangement effects on tsunami force has been obtained from these results.
