Optimization of Aeration Systems for Value-Added Crop Preservation

1.To solve using the finite element method and experimentally validate the equations that govern non-uniform airflow in food-grain storage structures. 2.To integrate non-uniform airflow into an existing finite element model of the stored grain ecosystem to evaluate alternative aeration systems and strategies for the control of stored-product insects. 3.To determine experimentally the permeability of corn as a function of moisture content and percentage of fines and to evaluate its effect on natural convection during non-aerated storage and forced convection during aerated storage. 4.To quantify the costs and benefits using an existing integrated pest management economic model, and to demonstrate the feasibility of partial ambient and chilled aeration at commercial grain facilities.
