摘要
本文给出了在饱和一非饱和土壤中,水,汽、热运动的耦合型数值模型及大气边界层模拟。计算所需输入的量为气象因素,土壤温度和水力特性。由于对耦合模型缺乏合适的解析解,故对两个模型分别用试验结果和解析解进行了验证,结果吻合较好。用此数值模型模拟了蒸发条件下的土壤水分运动问题。
A numerical model physically based on formulation of water—vaper—heat transport in saturated—unsaurated soils coupled with a lower atmosphere boundary layer modelling is presented. The inputs requisite for the computer simulation are weather data, soil thermal and hydraulic properties. The coupled numerical model is tested separately against the experimental result and analytical solution because of the scarcity of suitable analytical solution for the coupled problem. The coincidence of the numerical solution is excellent.
