Dispersion and Dispersivity Tensors in Saturated Porous Media with Uniaxial Symmetry

摘要: The coefficient of dispersion, D ij , and the dispersivity, a ijkl appear in expression for flux a solute saturated flow through porous media. We present detailed analysis these tensors an axially symmetric medium, e.g., stratified with alternating layers, show that such dispersivity is governed by six independent moduli. also constraints have to be satisfied at least two experiments are required order obtain values coefficients any three-dimensional medium domain.
