Single-phase flow velocimetry in a super wide bore spectrometer

Bruker’s super wide bore system equipped with the MiniSWB90 have been used to study the interpore space of a packed cylinder of particles. With the help of 3D MR microcopy images the pore’s structure are acquired and using the MR microscopies velocimetry measurement routine, the velocity vector field in the enclosed space is investigated, enabling to fully characterize the system, and infer the average molecular displacement propagators. In the image the packed cylinder is shown next to three images acquired with the MR microscopy setup which combines structural information with the velocity map in each spatial direction.
