Abstract

Based on the assumption that biofilms are impermeable, we investigated the mechanism and law of the influence of microbial growth non-uniformity on the permeability of porous media in the artificial recharge of groundwater. The relationship between the total permeability of porous media and that of cross section was developed and the coupled Lattice Boltzmann Method-Immersed Moving Boundary-Cellular Automata (LBM-IBM-CA) model was used to simulate the non-uniform microbial growth in porous media. Quantitative analysis was conducted on the impact of the grain sparsity of porous media on the non-uniformity of relative porosity changes and permeability decrease caused by microbial growth. The non-uniformity of relative porosity changes was innovatively introduced into the porosity-permeability relationship. The main results are as follows. (1) The non-uniformity of nutrient concentration distribution in porous media is the fundamental reason for the non-uniformity of microbial growth and relative porosity changes. (2) The non-uniformity of relative porosity changes increases with microbial growth for the porous media with smaller grain sparsity. However, the opposite situation occurs for the porous media with larger grain sparsity. (3) In the event of clogging of porous media, the pressure drop caused by biological growth accounts for more than 90 % of the total pressure drop. (4) In the power-law relationship of the porosity-permeability, the index of non-uniformity of relative porosity changes is closely related to the sparsity of the grain at the entrance of porous media.

期刊介绍: Advances in Water Resources provides a forum for the presentation of fundamental scientific advances in the understanding of water resources systems. The scope of Advances in Water Resources includes any combination of theoretical, computational, and experimental approaches used to advance fundamental understanding of surface or subsurface water resources systems or the interaction of these systems with the atmosphere, geosphere, biosphere, and human societies. Manuscripts involving case studies that do not attempt to reach broader conclusions, research on engineering design, applied hydraulics, or water quality and treatment, as well as applications of existing knowledge that do not advance fundamental understanding of hydrological processes, are not appropriate for Advances in Water Resources. Examples of appropriate topical areas that will be considered include the following: • Surface and subsurface hydrology • Hydrometeorology • Environmental fluid dynamics • Ecohydrology and ecohydrodynamics • Multiphase transport phenomena in porous media • Fluid flow and species transport and reaction processes
