摘要
给出了土壤非饱和水流运动方程和热流方程的耦合模型,采用第二类边界条件对方程求解。土壤湿度的拟合效果比由水流方程建立的模型精度提高近一倍。
In this paper,a coupled model for water end heat transfer in unsaturatedcropped soil is presented and its numerical solution is given under the second boundaryconditions. The fitting accuracy of the model for soil humidity is doubled as comparedwith that simulated by a single weter flow equation.
