Without external magnetic field flows are stable and pro-grade with respect to the rotation of the inner cylinder. More complex behaviors can arise when an axial or a transverse magnetic field is applied. Depending on the direction and strength of the field, multi-stable wavy states and bifurcations can occur. We uncover the phenomenon of flow pattern reversal as the strength of the magnetic field is increased through a critical value. In between the regimes of pro-grade and retrograde flow rotations, standing waves with zero angular velocities can emerge. A striking finding is that, under a transverse magnetic field, a second reversal in the flow pattern direction can occur, where the flow pattern evolves into pro-grade rotation again from a retrograde state. Flow reversal is relevant to intriguing phenomena in nature such as geomagnetic reversal. Our results suggest that, in ferrofluids, flow pattern reversal can be induced by varying a magnetic field in a controlled manner, which can be realized in laboratory experiments with potential applications in the development of modern fluid devices.","lang":"eng"}],"oa_version":"Published Version","department":[{"_id":"BjHo"}],"status":"public","article_type":"original","article_number":"18589","has_accepted_license":"1","date_created":"2018-12-11T11:52:53Z","citation":{"mla":"Altmeyer, Sebastian, et al. “Magnetic Field Induced Flow Pattern Reversal in a Ferrofluidic Taylor-Couette System.” <i>Scientific Reports</i>, vol. 5, 18589, Nature Publishing Group, 2015, doi:<a href=\"https://doi.org/10.1038/srep18589\">10.1038/srep18589</a>.","ama":"Altmeyer S, Do Y, Lai Y.
