    patterns for a mixed- flow drier is presented. The pressure pattern of air flow is obtained by numerically solving the partial differential equation modelling the flow. The finite element method as implemented in an IMSL package is used to obtain the numerical solution. The results of isobar calculations are compared with a full-scale model of a section of a conventional mixed-flow drier of the type manufactured by Law-Denis. The simulation pattern has a satisfactory agreement with the experimental data in the area where duct walls are parallel to each other. The difference between experimental and computation results was about 3% in this area. In the area under the inlet duct the experimental results are slightly lower. It is hypothesized that the orientation of kernels with respect to air flow has a significant influence on pressure drop in a bed of grain.
