二维Stokes波与多块浮冰相互作用数值模拟

Numerical simulation on the interaction between two-dimensional Stokes wave and multiple ice floes

该文基于Fluent软件,采用VOF模型中的明渠波浪边界条件,建立生成二维Stokes波浪的数值波浪水槽,并与解析解进行对比验证了生成波浪的准确性。基于此研究二维Stokes波浪与单块浮冰相互作用的特性,分析波浪作用下浮冰的运动和受力特点,以及波浪传播特性。在此基础上,研究二维Stokes波浪与多块浮冰相互作用,将波浪下多块浮冰与单块浮冰的响应进行对比分析,获得多浮冰的耦合效应。

Based on software Fluent,by using‘open channel wave boundary conditions’in VOF model,two-dimensional(2 D)Stokes wave in numerical wave tank is simulated,which is validated by the comparison with analytical results.On this basis,the interaction between 2 D Stokes wave and a single ice floe is studied.The motions and forces of the ice floe and the propagation of the wave are analyzed.Furthermore,the interaction between 2 D Stokes wave and multiple ice floes is studied.The responses of multiple ice floes under waves are compared with those of a single ice floe and the coupling effects of multiple ice floes are obtained.
