Journal of Applied Mathematics 2011: 1-41. doi:10.1155/2011/498098. dc.identifier.issn 1110757X dc.identifier.doi 10.1155/2011/498098 dc.identifier.uri http://hdl.handle.net/10754/334619 dc.description.abstract This paper begins with presenting a mathematical model for contaminant transport in the fractured vuggy porous media of a species of contaminant (PCP). Two phases are numerically simulated for a process of contaminant and clean water infiltrated in the fractured vuggy porous media by coupling mixed finite element (MFE) method and finite volume method (FVM), both of which are locally conservative, to approximate the model. A hybrid mixed finite element (HMFE) method is applied to approximate the velocity field for the model. The convection and diffusion terms are approached by FVM and the standard MFE, respectively. The pressure distribution and temporary evolution of the concentration profiles are obtained for two phases. The average effluent concentration on the outflow boundary is obtained at different time and shows some different features from the matrix porous media. The temporal multiscale phenomena of the effluent concentration on the outlet are observed. The results show how the different distribution of the vugs and the fractures impacts on the contaminant transport and the effluent concentration on the outlet. This paper sheds light on certain features of karstic groundwater are obtained. dc.language.iso en dc.publisher Hindawi Limited dc.rights This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. dc.rights Archived with thanks to Journal of Applied Mathematics dc.rights.uri http://creativecommons.org/licenses/by/3.0/ dc.title Numerical simulation of pollutant transport in fractured vuggy porous karstic aquifers dc.type Article dc.contributor.department Computational Transport Phenomena Lab dc.contributor.department Earth Science and Engineering Program dc.contributor.department Physical Science and Engineering (PSE) Division dc.identifier.journal Journal of Applied Mathematics dc.eprint.version Publisher's Version/PDF dc.contributor.institution Department of Mathematics, College of Science, Guizhou University, Huaxi, Guiyang 550025, China dc.contributor.affiliation King Abdullah University of Science and Technology (KAUST) kaust.person Sun, Shuyu kaust.person Kou, Jisheng refterms.dateFOA 2018-06-14T07:18:06Z
