Abstract
One of the effective protection facility against a huge tsunami is a seawall. The wave force of tsunami acting on such a seawall has been studied by many researchers so far. According to Takahashi et al. (1983), it is important to consider the following two factor for prediction of impulsive wave pressure. One is the angle between the wave front and the wall, and the other is compressibility of air. On the other hand, establishment of prediction method using numerical simulation has been attempted. As mentioned above, it is important to calculate the angle between the wave front and the wall, and in order to predict impulsive wave pressure accurately, a computational model which can treat complex interface deformation is necessary. In this study, we analyze wave pressure of solitary waves using gas-liquid two-phase simulator and examine its applicability. And also, we examine computational efficiency and speed of its simulator.
