Overview of Mathematical Model and Numerical Simulation in the Stored Grain Ecosystem

The stored grain ecosystem is an interdisciplinary and complex system, involving physical, chemical and biological field, which are also affected by the atmospheric environment outside warehouses or bins of stored grain. It is difficult to deal with the problems in the stored grain ecosystem by means of the conventional experimental methods. In recent years, the numerical simulation method has been widely used for the research on the physical and biological phenomena in stored grain ecosystem. In present paper, the various physical and biological and other factors in the stored grain ecosystem were briefly analyzed, and then main mathematical models, the numerical simulation method and the commonly used software of the stored grain ecosystem were also introduced. The advance in numerical research on air flow, heat and moisture migration, and biological phenomenon in the stored grain ecosystem are also reviewed, and the advantages of numerical simulation for the stored grain ecosystem and the future development trend were discussed.
