Tsunami Impact on Wall
According to Takahashi et al. (1983), it is important to consider the angle between the wave front and the wall, and compressibility of air for prediction of impulsive wave pressure. In order to predict impulsive wave pressure accurately, a computational model which can treat complex interface deformation is necessary. However, gas-liquid two-phase flow analysis is bad condition due to difference in density between water and air, and stability and convergence are poor. So, in this research, the calculation is stabilized in order to obtain accuracy, and we conducted a study on computational efficiency and speed.
