摘要
给出了混相驱对流-弥散方程的无量纲形式;采用高阶精度差分格式对其进行数值求解并应用于几个具体算例中。本文数值结果和算例给出的结果对比,充分验证了本文数值模型的可靠性和准确性。该数值模型可以用来研究诸如土壤或地下水污染物输运以及空气污染等领域里的传质问题。
The dimensionless form of convection-dispersion equation in miscible displacement is deduced. The higher-order scheme is implemented to solve the model. Several samples are given, in which the comparison between the experimental results and the numerical results validates the reliability and accuracy of the numerical model. This numerical model can be applied to study the mass transfer in many fields such as pollutant transport in soil or groundwater and air pollution.
