摘要

建立了基于时域有限差分法的二维氡输运数值模型。该模型由考虑扩散、平流和衰变机制的氡输运方程控制。该模型的目的是模拟氡浓度的演变过程，氡浓度的演变受土层的深度和扩散系数以及氡的速度和初始浓度等参数的影响。将得到的结果与解析解进行了比较，以证明该模型能够预测氡在土层多孔介质中运移的时空演变。

A Two-Dimensional Unsteady FDTD Model for Radon Transport with Multiple Sources Emanation from Soil Layers

A two-dimensional numerical model for radon transport based on the finite difference time domain (FDTD) method have been developed. The model is governed by the radon transport equation taking into account the mechanisms of diffusion, advection, and decay. The purpose of this model is to simulate the evolution of radon concentration which can be influenced by various parameters including depth and diffusion coefficient of the soil layer plus the velocity and initial concentration of radon. The obtained results were compared to an analytical solution to demonstrate the ability of this model for predicting the spatio-temporal evolution of radon transport in the porous media of soil layers.
