Quantitative Measurement of Velocity and Dispersion via Magnetic Resonance Imaging

Three pressure-driven flows of increasing complexity were examined, including flow through a water-saturated bed of randomly packed spheres, a Taylor-Couette-Poiseuille flow reactor, and the interstitial space between the blades of a rotating partitioned pipe mixer. Key findings show that a snapshot FLASH spin-tagging sequence can provide time-resolved visualization of 3-D swirling flows in domains with rotational symmetry. In addition, an echo planar imaging-based phase contrast sequence can be applied for the direct measurement of the Eulerian velocity fields in more general swirling flows. Longitudinal dispersion measurements in the packed bed and partitioned pipe mixer corroborated previous measurements and facilitated the development of functional relationships between interstitial space flow and mixing behavior.
