Capabilities of NMR Relaxometry Using Magnetic Nanoparticles for the Analysis of Fluid Motion in a Porous Medium

The dependence of the transverse relaxation time T 2 on the liquid, flow velocity in a porous medium (for the water and water suspension of magnetic nanoparticles (MNPs)) is studied. The T 2 value allows measuring the filtration velocity of a liquid on the order of 0.05 mm/s. MNPs in a small concent...

Description
Summary:The dependence of the transverse relaxation time T 2 on the liquid, flow velocity in a porous medium (for the water and water suspension of magnetic nanoparticles (MNPs)) is studied. The T 2 value allows measuring the filtration velocity of a liquid on the order of 0.05 mm/s. MNPs in a small concentration decrease T 2 but at the same time the dependence of T 2 on the liquid’s velocity becomes more pronounced.
