“…Experiments have been conducted to extract time-averaged gas velocity and gas concentration in different heterogeneous regions of a gas-solid flow ( Figure 3 B) ( Pavlin et al., 2007 ). Measurements have provided insights into gas flow through rock cores ( Wang et al., 2005 ), packed particles ( Sankey et al., 2009 ), and fluidized particles ( Boyce et al., 2016 ) as well as turbulent gas flow around obstacles ( Gauthier and Newling, 2018 ; Newling et al., 2004 ).…”

Summary Geological flows—from mudslides to volcanic eruptions—are often opaque and consist of multiple interacting phases. Scaled laboratory geological experiments using analog materials have often been limited to optical imaging of flow exteriors or ex situ measurements. Geological flows often include internal phase transitions and chemical reactions that are difficult to image externally. Thus, many physical mechanisms underlying geological flows remain unknown, hindering model development. We propose using magnetic resonance imaging (MRI) to enhance geosciences via non-invasive, in situ measurements of 3D flows. MRI is currently used to characterize the interior dynamics of multiphase flows, distinguishing between different chemical species as well as gas, liquid, and solid phases, while quantitatively measuring concentration, velocity, and diffusion fields. This perspective describes the potential of MRI techniques to image dynamics within scaled geological flow experiments and the potential of technique development for geological samples to be transferred to other disciplines utilizing MRI.
