数値波動水槽における開境界処理へのニューラル・ネットワークの適用

抄録

In this paper, a new open boundary treatment technique on the probrem of irregular wave simulation in numerical wave tanks is proposed. A neurl network model is applied in the present study to set up an open boundary where outgoing waves can pass it smoothly without affecting the solution inside the computational domain. An artificial velocity reduction zone is also installed adjacent to the open boundary to assist the treatment at the boundary. By comparison of the performance of the tanks with the alternative techniques, the advantage of the proposed one is shown.
