| 中文摘要 | the hydrodynamic research on water wave and structures is the theoretic base of dynamic response of oceanic structure. in this article, the simplified two-dimensional model is introduced to simulate three-dimensional structures approximately. analytical and numerical methods are used respectively to solve the problem of the interaction of linear waves with structures in a two-layer fluid of infinite depth. first of all, the background and significance on the interaction of linear waves with structures in a two-layer fluid are introduced in chapter 1, and then the research progress is presented. in chapter 2 the interaction between linear waves and a single horizontal circular cylinder is investigated by use of an analytic method (multipole expansion method), and then extended to an array of infinitely horizontal circular cylinders with linear waves. in chapter 3 the numerical method (boundary element method) is presented to solve the radiation and diffraction of linear waves with structures. in chapter 4 the computational results are emphasized on the interaction of linear waves with an array of infinitely horizontal circular cylinders and rectangular cylinders, and some arbitrary shape cylinder on different geometrical and physical conditions. conclusions and perspectives are presented in the end. in this article the interaction of liner waves with horizontal circular cylinders in a two-layer fluid was solved by use of the multipole expansion method, and we find the forces on two circular cylinders is determined by the located layer of the fluid, the influences of the added two cylinders on the forces of the former two cylinders are small in low and high incident wave frequency, but in the intermediate incident wave frequency, their influence may be appreciable, the effect of reflection and transmission energies is related with the located layer of the fluid and the incident wave mode; then the boundary element method is used to treat the problem on cylinders of arbitrary shape, and we get that the forces on the cylinder is related with the relative width、submerged depth and the density ratio, and the oscillations of wave forces can be found on two submerged rectangular cylinders, those new research results are useful for the design of ocean structures. |
