二层流体中圆弧型贯底式防波堤的绕射波浪力
The diffracted wave forces on arc-shaped bottom-mounted breakwater in two-layer fluid
摘要
Abstract
Based on the wave diffraction theory in the two-layer fluid,and with the use of eigenfunction method,the wave potentials of ocean surface wave and internal wave diffraction in two-layer fluid caused by arc-shaped bottom-mounted breakwater are derived,and accordingly the wave forces and moments on breakwater are analytically calculated. The result shows that in two-layer fluid,the maximum dimension-less wave loads caused respectively by surface wave and internal wave may have the same order of magni-tude. The relative variation of incident wave angle,two layer fluid density ratio,sea water condition and breakwater structure geometry condition may have some influence on diffracted wave effects,and there are some differences between the variation of surface wave effect and that of internal wave effect. Because of interference from internal wave,the diffracted effects of surface wave in two fluid are different from that of surface wave in uniform ocean.关键词
