Model trickle-bed

The MRI measurement is made by positioning the model trickle-bed reactor within the bore of the superconducting magnet, with the imaging section located... 

Fig. 5.2.2 (a) The upper section of a typical the superficial flow direction (down the col-model trickle-bed reactor used in MRI studies, umn, z) have been measured 2D slice sections (b) MR image of water flowing within a fixed through the 3D image are shown with slices bed of spherical glass beads the beads have no taken in the xy, yz and xz planes indicated.
