Multiphase flows are of major importance in today's industrial processes as many products originate from gas-liquid reactions. The hydrodynamics within the wake behind the bubbles is essential as product selectivity is determined by the residence times in these mixing zones. Magnetic resonance imaging (MRI) offers a wide range of options for the investigation of multiphase flows. Here, non-invasive MRI flow measurements of buoyancy-driven N-2 Taylor bubbles, spatially fixed inside a countercurrent flow of water, are performed. An experimental setup is presented, enabling the generation of Taylor bubbles inside a horizontal bore MRI scanner. Furthermore, a suitable MRI sequence allowing a time-dependent analysis of the present flow field is described. The obtained MRI results are qualitatively compared to PIV images acquired in the same setup.
