In the present work, we investigate the hydrodynamic behavior of a turbulent bore, such as tsunami bore and tidal bore, generated by the removal of a gate with water impounded on one side. The bore generation system is similar to that used in a general dam-break problem. In order to the numerical si...

| 단파란? | 시·공간적으로 급변하는 불연속 흐름으로 정의되는 단파(bore)는 지진해일파, 조석파 혹은 댐파괴류 등에서 선단부의 전후에 형성되는 큰 수위차에 의해 발생하고, 경우에 따라 매우 빠른 전파속도를 갖는 충격파가 연안구조물에 큰 충격파력(Ramsden, 1993, 1996; Abdolmaleki et al., 2004)과 세굴(Tonkin et al. | |
| CIP법을 다차원으로 확장하는 방법에서 1차원 CIP법을 3차원으로 확장하는 직접법의 장점과 단점은? | 이와 같은 개념에 기초한 1차원 CIP법을 다차원으로 확장하는 방법에는 1차원의 다항식을 직접 다차원공간에 확장하여 적용하는 직접법과 각 차원을 분리하여 계산하는 분리해법이 고려될 수 있다. 1차원 CIP법을 3차원으로 확장하는 직접법의 경우는 수치계산시에 요구되는 기억량(메모리 점유율)이 작다는 장점을 지니는 반면에, 3차원 보간함수를 산정하는 경우에 과다한 10의 미지수가 포함되기 때문에 3차원으로의 확장에는 비효율적인 것으로 판단된다. 따라서, 본 연구에서는 Takewaki et al. | |
