Flow behaviors in a porous system employing multi-hole channels with or without surface ceramics layer, which is commonly used for filtering process in industrial applications, are investigated by using Magnetic Resonance Imaging (MRI) for measuring axial velocity distribution inside the channels and numerical calculation for pressure distribution inside the porous filter. It is revealed that flow in the filter without surface ceramics layer shows non-uniform axial velocity distribution where channels nearest to the outside annulus only shows large axial velocity. On the other hand, in the case with surface ceramics layer, uniform axial velocity distribution is observed, because a ratio of flow resistance of surface layer to that of porous base dominates flow uniformity.
