Advances in research for numerical simulation of contaminant transport and flow in North China type fracture-karst media

简要回顾了近几十年来我国北方型裂隙岩溶水流及污染物运移数值模拟方面的研究成果,评述了裂隙岩溶水资源评价和污染物运移模拟的计算方法和模拟技术,其中对一些与数值模拟相关的重要问题、近年来研究的热点问题,如模型参数识别及其尺度效应问题、数值弥散和数值振荡问题、Non Darcy流和Non Fickian运移问题以及随机方法研究等进行了重点评述,对已有的解决办法进行了比较和对照,并探讨了今后的研究趋势。

The studies on numerical simulation of contaminant transport and flow in North China type fracturekarst media last decades are reviewed, the numerical methods and computational techniques which have been developed to solve problems of contaminant transport and flow are examined The key and wellnoticed problems in connection with the numerical simulation, which include parameter identification and scale effect, numerical dispersion and libration, nonDarcy flow and NonFickian transport, study of stochastic methods, and so on, are highlighted Attempts have been made to compare and contrast representative numerical methods, and the direction for future research is suggested
