Description

<p>In the field of coastal engineering, it is important to evaluate the wave pressure due to Tsunami bore for the maintenance of coastal structures. The purpose of this study is to improve the quasi-compressibility source term for Moving Particle Semi-implicit (MPS) method to calculate the pressure value stability. As a verification of accuracy, the hydrostatic pressure of a stationary fluid was simulated. The simulation results showed the high accuracy compared with the theoretical value. Furthermore, as an application to the coastal engineering field, Tsunami bore was simulated. The relationship between impact pressure and standing wave pressure, standing wave pressure and water elevation in front of seawall, and standing wave pressure and offshore wave height showed satisfactory results compared with the experiment.</p>
