4D Synchrotron X-Ray Multi Projection Imaging (XMPI) for studying multiphase flow dynamics and flow instabilities in porous networks
Patrick Wegele, Zisheng Yao, Jonas Tejbo +11
Flow instabilities such as Haines jumps in porous media are common phenomena that occur on sub-second timescales. X-rays are particularly suitable for investigating these processes…

Time-resolved X-ray radiography of through-thickness liquid transport in partly saturated needle-punched nonwovens
Patrick Wegele, Zisheng Yao, Jonas Tejbo +7
Nonwoven fibre networks underpin filtration, insulation and geotextiles, where liquid uptake, redistribution and release govern performance. In needle-punched felts, barbed needles…
