Similarly, in the field of process engineering, understanding flow parameters and component distribution is critical, particularly in the study of stirred tank reactors (STRs). Traditional medical MRI scanners, which are typically designed for horizontal orientation, present certain limitations for investigating STRs. The non-intrusive nature of MRI, combined with its ability to analyse opaque and complex mixtures offers detailed, three-dimensional insights into STRs. These insights help tackling the significant challenge of understanding the complex hydrodynamics of STRs, thus fasten optimization and ease scale-up efforts [1]. In this study we use MRI to investigate liquid flow in an STR model of an inner diameter of 188 mm and a height of 1000 mm. All measurements were performed on a vertical 3T MRI system, optimized for process imaging. The open radiofrequency shielding design and the vertical orientation of the MRI system, allow to accurately control the stirrer speed with an electric motor. Different impeller types and rotational speeds and their effects on the fluid hydrodynamics are studied. In the future we are planning to investigate realistic industrial conditions and complex multi-phase material systems. We anticipate these measurements to enhance our understanding of the complex hydrodynamics within STRs. Moreover, the measurements can be used to test and improve the accuracy of computational fluid dynamics (CFD) models for process design and optimization.
