Fluid Force Acting on Tanks due to Tsunami Inundation Flow

Abstract

Tsunami force acting on tanks was discussed based on the experimental results ranging from subcritical flow to supercritical flow. The water level around the tank and the tsunami pressure were also measured. The comparison between the pressure profile and the water level around the tank shows that the pressure is lower than the hydrostatic pressure under the supercritical flow while that under the subcritical flow is close to the hydrostatic pressure. The mechanism on the pressure fields was discussed. The tsunami force acting on multiple tanks was also measured and effects of the tank disposition on the force were discussed.
