Finite-element prediction of non-uniform airflow in fixed beds of wheat.

Resistances to horizontal and vertical airflow through clean, dry wheat (Triticum aestivum) were determined. Airflow resistance data, expressed in a functional relationship, were used in a mathematical model describing non-uniform flow of air in stored grain. The mathematical model was solved using the finite-element method to predict static pressure patterns in 6 laboratory-scale configurations. Predicted pressures compared well with the pressures measured in 47 tests, except for points near the grain surfaces.
