Abstract
In order to develop the simple network model of interstitial flow trough a packed bed, three-dimensional void images measured by magnetic resonance imaging (MRI) were divided into polyhedrons as fluid pass. By assuming that flow resistance through one plane of a polyhedron is the inverse square of its plane area, closed circuits of flow resistances in the packed bed were constructed. By solving the matrix of circuits, flow rate through each polyhedron was calculated and compared with the velocity map measured by MRI.
