摘要:Using fluid-body interaction mechanics, the motion proceeds of a floating body was numerically simulated in regular wave, which was implemented in a wave making and absorbing numerical flume. As the application case of a box-type floating breakwater with mooring systems, dynamic characteristics of the floating body among the trapezoid, 2, 3order single step method and BEM based on potential flow theory were compared. The results indicate that the trapezoid and 2, 3order single step method which were in good agreement with the BEM results has prospective accuracy and convergence in regular wave. This paper pro-posed an new technique of dynamic mesh with full 2D-3 degrees of freedom multiply structured grids, which realized the joint movement of all directions, and made sure that grids had not any distortion. The computation time, precision and meshing remained fairly well-contained.
