3D Imaging of On-Chip Porous Medium Using X-ray Laminography: Application to Reactive Flow Dissolution at Small Scales

In this study, X-ray laminography is used to monitor the evolution of a model 3D packed bed porous medium on chip (micromodels) undergoing reactive flows. The obtained images are compute fluid flow patterns and develop insights into dissolution mechanisms. This study first proof concept with controlled micromodels, could later be extended towards deeper understanding precipitation processes occurring in media at microscale, mechanisms which relevant many industrial areas including catalysis, geochemistry, energy, waste storage deep geological formations, etc.
