本文研究了在法向电场作用下，毛细重力波在两种介质流体界面上的传播。假定上层流体的密度比下层流体的密度小得多。线性和弱非线性理论进行了研究。在其他极限配置的结果的连接进行了讨论。行波解的完全非线性计算是通过边界积分方程方法实现的。给出了周期波、孤立波和广义孤立波。详细讨论了广义孤立波的分叉问题。
In this article, we consider capillary-gravity waves propagating on the interface of two dielectric fluids under the influence of normal electric fields. The density of the upper fluid is assumed to be much smaller than the lower one. Linear and weakly nonlinear theories are studied. The connection to the results in other limit configurations is discussed. Fully nonlinear computations for travelling wave solutions are achieved via a boundary integral equation method. Periodic waves, solitary waves and generalised solitary waves are presented. The bifurcation of generalised solitary waves is discussed in detail.
