Crapper精确解在常涡流波动中的新应用

A new application of Crapper's exact solution to waves in constant vorticity flows

Vera Mikyoung Hur, Jean-Marc Vanden-Broeck

摘要:

在1957年克拉珀发现了一个精确的解决方案毛细波传播的表面无旋流动的无限深。在这里,我们提供了结论性的分析和数值证据表明,克拉珀波使一个周期性的行波传播的轮廓,在没有重力和表面张力的影响,在一个恒定的涡量流。这是通过在小振幅参数下构造三阶斯托克斯展开和通过数值计算大振幅波来实现的。

英文摘要:

In 1957 Crapper found an exact solution for capillary waves propagating at the surface of an irrotational flow of infinite depth. Here we provide conclusive analytical and numerical evidence that a Crapper wave makes the profile of a periodic traveling wave propagating, in the absence of the effects of gravity and surface tension, in a constant vorticity flow. This is achieved by constructing a Stokes expansion up to the third order in a small amplitude parameter and by numerically computing large amplitude waves.
