摘要

我们考虑用欧拉方程描述有限深度的流体层。冰盖由几何非线性弹性基尔霍夫-洛夫板模拟。冰盖下流体粒子的轨迹是在非线性表面行波的场中发现的，该非线性表面行波在无限远处迅速减小。分析中使用了描述水冰界面上振幅很小但有限的经典孤波类型的波结构解的明确渐近表达式。

Trajectories of Fluid Particles Under an Ice Cover in the Field of a Solitary Bending-Gravity Wave

We consider a fluid layer of finite depth described by Euler equations. The ice cover is simulated by a geometrically nonlinear elastic Kirchhoff–Love plate. The trajectories of the fluid particles under the ice cover are found in the field of a nonlinear surface traveling wave rapidly decreasing at infinity. The analysis uses explicit asymptotic expressions for the solutions describing the wave structures of the type of a classical solitary wave with a small but finite amplitude on the water–ice interface Asymptotic solutions for the velocity field generated in the bulk of fluid by these waves are also used.
