畸形波的模擬及其與浮式結構物的相互作用分析
[Abstract]:The deformable wave is a kind of disaster wave with huge wave height, which is destructive to navigation and marine engineering equipment. At present, the theoretical equation of deformable wave has its limitations, and its generating mechanism and influencing factors are still unclear. Due to the low probability of abnormal waves and less measured data, the research work is still in the initial stage. There is less research on the interaction between deformable waves and marine floating structures. In this paper, the deformable waves and their interactions with floating structures are studied based on CFD method. The main contents and results are as follows: (1) based on hydrodynamic theory and structural dynamics theory, The fluid-solid coupling mathematical model of wave and structure interaction is established, including the incompressible continuity equation and N-S equation, the linear elastic structural dynamics equation after finite element discretization, and the interface between free liquid surface and solid-liquid interface. (2) based on the traditional linear wave superposition theory, the CFD software Fluent is developed to simulate the deformable waves in two-dimensional and three-dimensional numerical wave pools, respectively. The limitation of limit-focused wave model and the feasibility of combining wave model to simulate deformable wave are verified by calculation. (3) based on the principle and method of bidirectional fluid-solid coupling and slice theory, A numerical model of the interaction between deformable waves and rigid floating structures is established in a two-dimensional numerical wave pool. The wave surface variation and the time history of motion of the structures are obtained, and the calculated results are compared with the experimental results. The feasibility of this method is verified. On this basis, through a series of calculation conditions, the variation of wave surface around the structure, motion response, surface water level and slamming load are obtained, and the mechanism of deck wave rolling is analyzed. Numerical simulation of strong nonlinear process of spatter and other fluids. (4) the coupled numerical model of the interaction between deformable wave and aluminum floating box is established in the three-dimensional numerical wave pool, and the motion response of the floating box in the deformable wave is calculated. Hydrodynamic response and structural response etc.
