多孔介质内部热质传递的等效耦合扩散模型的推导及其应用

INDUCTION AND APPLICATION OF EQUIVALENT COUPLING DIFFUSION MODEL ON HEAT-AND-MASS TRANSFER INSIDE FOROUS MEDIA

基于Whitaker的体积平均方程 ,在不附加任何新的假设的基础上 ,对多孔介质内部热质传递的等效耦合扩散模型进行推导 ,得出了多孔介质内部热质传递的等效耦合扩散模型。并应用该模型对瓷质砖体干燥过程进行了数值模拟 。

In the base of Whitaker's local volume average equations and not adding new analyses,the model of heat and mass transfer equivalent coupling diffusion of porous media is induced.Appling the model to numerical analyses of the porcelain tile during the body drying process,the simulation outcome fits with experiment outcome.
