铁磁流体表面的轴对称孤立波

Axisymmetric solitary waves on the surface of a ferrofluid

Elise Bourdin, Jean-Claude Bacri, Eric Falcon

摘要:

我们报告的第一个观察到的轴对称孤立波的表面上的圆柱形磁流体层周围的载流金属管。根据磁力和毛细力之间的比率,观察到的海拔和抑郁症孤立波的配置文件与理论预测的基础上的磁模拟的Korteweg-deVries方程。我们还报告了第一次测量的速度和轴对称线性波传播的圆柱形铁磁流体层,发现与理论预测吻合良好的色散关系。

英文摘要:

We report the first observation of axisymmetric solitary waves on the surface of a cylindrical magnetic fluid layer surrounding a current-carrying metallic tube. According to the ratio between the magnetic and capillary forces, both elevation and depression solitary waves are observed with profiles in good agreement with theoretical predictions based on the magnetic analogue of the Korteweg-deVries equation. We also report the first measurements of the velocity and the dispersion relation of axisymmetric linear waves propagating on the cylindrical ferrofluid layer that are found in good agreement with theoretical predictions.
