摘　　要：基于多孔介质传热传质理论和计算流体动力学基础,采用FLUENT软件对玉米仓内的温度进行了模拟,分析了随着时间的变化玉米仓内的温度分布规律,以便适当地控制玉米的温度和水分,从而达到安全储藏的目的。并且通过实验测量同一储存点的温度分布来验证该模型,结果表明不同半径和深度处的预测温度和测量温度能较好的吻合。The temperature in bulk corn in warehouse was simulated by software FLUENT based on the theory of heat and mass transfer in porous medium and computational fluid dynamics （CFD）. The temperature distribution in bulk corn changed along with the time was analyzed in order to properly control the temperature and moisture in corn heap for safe storage. The model was verified by experiments to measure the temperature in the same points, which showed that the temperatures predicted and measured in various radii and depths were close.
