... to be semi-infinite extended and of uniform properties. A boundary integral equation is developed for the velocity potential based on a specific Green function, which satisfies both the boundary conditions on free-surface and the semi-infinite ice sheet. Numerical results show oscillatory behaviours...

Paper Number: ISOPE-I-15-743
... Abstract The conventional boundary integral equation for the solutions of linear wave-body interactions is extended to include the radiation solutions due to oscillatory pressures applied on the free surface. Coupled with the constraints which determine the pressure, the extended integral...

... successes in simulating non-linear free surface waves are attributed to the boundary element methods. However, it is noted that other numerical methods can also give reasonable solutions(Kim et al., 1998, and Muzaferija et al., 1997). boundary integral equation boundary incident wave biquadratic...

.... The wave elevation recorded at a few locations along the tank are used for the estimate of the amplitude spectrums, energies and skewnesses. It is found from the study that the energy dissipates and the skewness reduces as the wave progresses along the tank. In solving the boundary integral equation...

... to the numerical methods. Among many available numerical methods the one that based on the boundary integral equation has been applied successfully to investigate the scattering phenomenon by many researchers, e.g. Kitahara (1985), Achenbach and Kitahara (1986), etc., just mention a few. The study of a interface...
