Abstract
A theoretical study on the hydraulic conductivity of fully saturated anisotropic granular materials for a 2D fluid flow has been made by making use of the microstructure tensor as the anisotropy descriptor. The assemblage of particles was assumed to be the representative elementary volume of materials with void spaces as a multiply-connected continuum through which a Stokesian flow can pass. The Navier–Stokes equations have been then solved to find the mean velocity vector under different pressure boundary conditions. A tensorial form of the hydraulic conductivity with constants being functions of the invariants of the microstructure tensor, as the geometric measure of the anisotropy, has been presented based on a number of realizations for different GSD curves. Verifications with available experimental data exhibit a reasonable accuracy of the suggested equation.
期刊介绍:
Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science.
These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations.
>> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa.
The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
