论文摘要
我们显示并比较了圆柱形容器中潮汐样结构的电磁产生的数值和实验结果，该血管中充满了共晶液体金属合金Gainsn。使用各种强度和频率的场来驱动液态金属流动。研究了场变化对流动幅度和结构的影响。结果代表了未来的Rayleigh-Bénard实验的基础，在该实验中，预期调制的潮汐状流动扰动将同步大规模循环的典型荡妇模式。太阳中的螺旋性的类似夹带机制可能是导致太阳能发电机与潮汐占主导地位的行星金星，地球和木星的对准周期的同步。
We show and compare numerical and experimental results on the electromagnetic generation of a tide-like flow structure in a cylindrical vessel which is filled with the eutectic liquid metal alloy GaInSn. Fields of various strengths and frequencies are applied to drive liquid metal flows. The impact of the field variations on amplitude and structure of the flows is investigated. The results represent the basis for a future Rayleigh-Bénard experiment, in which a modulated tide-like flow perturbation is expected to synchronize the typical sloshing mode of the large-scale circulation. A similar entrainment mechanism for the helicity in the Sun may be responsible for the synchronization of the solar dynamo with the alignment cycle of the tidally dominant planets Venus, Earth and Jupiter.
