| Abstract: | Based on the theory of heat and mass transfer in porous media,a mathematical model of heat and moisture transfer in stored grain was proposed during cooling and drying ventilation.It was used to simulate the changes of grain temperature and moisture content by the way of CFD and the basic law of the heat and moisture transfer in stored grain during cooling and drying ventilation was discussed. |
