摘要
基于多孔介质传热传质的理论,建立了一种冷却干燥通风过程中粮仓内热湿耦合传递的数学模型。借助数值模拟的方法,对冷却干燥通风过程中粮仓内温度和水分的变化进行了模拟研究,得到了冷却干燥通风过程中粮堆内部热量传递和水分迁移的基本规律。
Based on the theory of heat and mass transfer in porous media, a mathematical model of heat and moisture transfer in stored grains was proposed during the cooling and drying ventilation.It was used to simulate the changes of grain temperature and moisture content by the way of CFD and obtained the basic law of the heat and moisture transfer in stored grains during the cooling and drying ventilation.
