| Abstract: | The grain and the ambient temperature control are the key factors in safe storage of grain. The temperature field of grain heap is simulated and researched by Computational Fluid Dynamics （CFD）. The simulation schemes, including method, parameter and process, in two mathematical models, static state and mechanical ventilation state, are described. The development trend and application of the mechanical ventilation techniques and CFD methods in safe storage of grain are reviewed. It is valuable in application of the technique to monitor and control the change of temperature field and flow field in real time. |
