Abstract
<p> When tsunami reaches a coastal area and intrudes into the water intake facility of the power plant, it may cause damage to the facilities and flooding of the power plant. In this study, we carried out hydraulic experiments and three-dimensional numerical simulations using CADMAS-SURF/3D in order to clarify the tsunami flow process into the water intake facility. In some cases, the flow velocity in the pump room was underestimated in the numerical simulation compared to the experiment. Because the reproducibility of turbulence near the wall was considered as one of causes for the underestimation, we introduced the low-Reynolds-number k-ε model to the numerical model, and confirmed the accuracy improvement of the numerical model. From the results of the hydraulic model experiments and the numerical simulation, it was found that the volume of water intake and the length of the pump room have an influence on the flow process of tsunami intruding into the water intake facility.</p>
