摘要：
Based on a simplified two-layer fluid model, the reflection and transmission characteristics of box structures were investigated in a two-layer fluid. In order to investigate the complex structures, a linearized frequency-domain model was developed by using a series expansion in the external domain and a higher-order boundary method in the internal domain. The continuity boundary condition was employed at the interface between the internal and external domains. In the internal domain, a Rankine source was used to avoid calculating a complex Green's function for the wave equation, and the velocity potentials on both the free surface and the internal surface were obtained directly. By comparison with the analytic results based on series expansion and verification of the energy-conservation principle, the proposed model was validated. By computing the reflection and transmission coefficients with the proposed model, the transformation between the two wave modes when the waves flow past box structures was analyzed and the reflection and transmission features were discussed. © 2016, Editorial Department of Journal of HEU.
