A 3-D Time-Domain Coupled Model for Nonlinear Waves Acting on A Box-Shaped Ship Fixed in A Harbor

Abstract：A 3-D time-domain numerical coupled model is developed to obtain an efficient method for nonlinear waves acting on a box-shaped ship fixed in a harbor.The domain is divided into the inner domain and the outer domain.The inner domain is the area beneath the ship and the flow is described by the simplified Euler equations.The remaining area is the outer domain and the flow is defined by the higher-order Boussinesq equations in order to consider the nonlinearity of the wave motions.Along the interface boundaries between the inner domain and the outer domain,the volume flux is assumed to be continuous and the wave pressures are equal.Relevant physical experiment is conducted to validate the present model and it is shown that the numerical results agree with the experimental data.Compared the coupled model with the flow in the inner domain governed by the Laplace equation,the present coupled model is more efficient and its solution procedure is simpler,which is particularly useful for the study on the effect of the nonlinear waves acting on a fixed box-shaped ship in a large harbor. 作者： Author： WANG Da-guo[1]  ZOU Zhi-li[2]  THAM Leslie George[3] 作者單位： Center for Material Failure Modeling Research, Dalian University, Dalian 116622, China ;The State Key Laboratory of Coastal and Offshore Engineering, Department of Civil Engineering, Dalian University of Technology, Dalian 116024, China;Department of Civil and Structural Engineering, The University ofHong Kong, Hong Kong, ChinaThe State Key Laboratory of Coastal and Offshore Engineering, Department of Civil Engineering, Dalian University of Technology, Dalian 116024, ChinaDepartment of Civil and Structural Engineering, The University ofHong Kong, Hong Kong, China 期 刊： 中國(guó)海洋工程（英文版）   ISTICEISCI Journal： China Ocean Engineering 年，卷(期)： 2011, 25(3) 分類號(hào)： U661.3 Keywords： nonlinear waves    coupled model    Boussinesq equations    Euler equations    機(jī)標(biāo)分類號(hào)： P7 U66 機(jī)標(biāo)關(guān)鍵詞： Ship    Nonlinear Waves    domain    coupled model    nonlinear waves    Boussinesq equations    numerical results    Laplace equation    efficient method    ship    flow    experiment    interface    solution    physical    in order    area    defined    study    Euler 基金項(xiàng)目： A 3-D Time-Domain Coupled Model for Nonlinear Waves Acting on A Box-Shaped Ship Fixed in A Harbor[期刊論文]  中國(guó)海洋工程（英文版） --2011, 25(3)A 3-D time-domain numerical coupled model is developed to obtain an efficient method for nonlinear waves acting on a box-shaped ship fixed in a harbor.The domain is divided into the inner domain and th...
