二维Stokes波与多块浮冰相互作用数值模拟
|
摘要
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.
