In order to explain the gas flow patterns in nonuniformly packed beds, a theoretical model considering the cross flow effects was developed and exact solutions on gas velocities and pressures were derived. The model was found to satisfactorily represent the experimental results of the pressure profiles in the bed, verifying the validity of this model. Further, it was confirmed that the considerable cross flow was caused in such beds by the axialy nonuniform flow resistance. Even though observed gas flow patterns neighboring the end of the beds would be similar to those calculated from parallel model, the inner gas flow patterns should be appreciably different from predictions by any noncross flow model as the parallel one. So consequently, special attention should be paid to the fact in experimental investigations of gas flow in nonuniform packed beds.
