Investigation of dynamic liquid distribution and hold-up in structured packings using ultrafast electron beam X-ray tomography

Qualitative and quantitative insights into multiphase flow in ceramic sponges using X-ray computed tomography

“…They investigated the liquid distribution in a trickle bed reactor, static and liquid hold-up in structured packings, and the interfacial area distribution. Furthermore, Green et al (2007), Janzen et al (2013), Mahr (2007) and Schmit and colleagues investigated the hydrodynamic properties in structured packings using X-ray tomography. All authors compare a dry packing with a wet (with water flowthrough) packing to describe the hydrodynamics.…”

Rate-based modelling and simulation of distillation columns with sandwich packings

“…This gap can be closed using, e.g., tomographic measurements. Janzen et al [21] have shown that the ultrafast electron beam X-ray tomography can be applied to determine the dynamic liquid distribution and the hold-up in structured packings under flooding condition.…”

Maldistribution susceptibility of monolith reactors: Case study of glucose hydrogenation performance

“…For example the effect of particle size and solid fraction on the intrinsic flow behavior in slurry bubble columns including gas bubble size and holdup distribution was tomographically studied . The imaging technique was further applied to visualize and characterize the dynamic liquid distribution of the counter‐current flow in structured packings up to the flooding point as the upper operation limit . The X‐ray technique also allowed revealing bubble dynamics in three‐dimensional gas–solid fluidized beds and to quantify the dispersive gas mixing in static mixers …”
