论文摘要
我们介绍了在液态 - 金属雷尼德（RB）实验中的螺旋性在潮汐样电磁强迫的影响下使用Azimuthal azimuthal波数M = 2的结果。我们表明，对于临界强度，在纵横比统一的圆柱形容器中，典型的大规模循环（LSC）受到潮汐状强迫的时期的夹带，从而导致同步的螺旋性振荡在两个半空间中具有相反的迹象。获得的实验结果与数值模拟一致并支持。太阳速素中的螺旋性的类似夹带机制可能是由11。07年的三重三重息套管对准周期的太阳能发电机对太阳能发电机的惊人同步。
We present results on the synchronization of the helicity in a liquid-metal Rayleigh-Bénard (RB) experiment under the influence of a tide-like electromagnetic forcing with azimuthal wavenumber m=2. We show that for a critical forcing strength the typical Large Scale Circulation (LSC) in the cylindrical vessel of aspect ratio unity is entrained by the period of the tide-like forcing, leading to synchronized helicity oscillations with opposite signs in two half-spaces. The obtained experimental results are consistent with and supported by numerical simulations. A similar entrainment mechanism for the helicity in the solar tachocline may be responsible for the astonishing synchronization of the solar dynamo by the 11.07-year triple synodic alignment cycle of the tidally dominant planets Venus, Earth and Jupiter.
