Fluid penetration method is applied in order to evaluate the non-uniformity of a particle bed structure. The apparatus developed consists of a cubic sample box which can be set on either surface. The pressure drops across the packed bed in the packing direction and its perpendicular direction were measured. The fluid penetration resistance in gravitational direction (=packing direction) was higher than that in the perpendicular direction, and the difference depended on the particle size and shape.<br>In order to find the relationship between the differences and the orientation of particles to the packing direction in a packed bed, experiments were conducted using a model packed bed consisting of uniform cylinders with a diameter of 4mm and a length of 100mm. A correlation was obtained between the orientation angle of cylinder axis to the packing direction and the ratio of specific surface area in perpendicular direction to that in the gravitational direction which were determined by the pressure drop measurements. Non-uniformity of a packed bed structure can be evaluated with the orientation angle to the packing direction using the obtained correlation.
