Transport of acridine in saturated porous media.
The effects of the aqueous solution pH, temperature, initial solute concentration and non-equilibrium processes on the transport of acridine in saturated porous media (silica) were investigated in a series of continuous-flow column experiments. The enthalpy of the adsorption reaction was more exothermic when the solution pH was above acridine's pKa (5.6) than when it was below. The extent of ad...
متن کاملWaves in Partially Saturated Porous Media
E orts to extend the theory of poroelasticity to semilinear and nonlinear elastic response, to partially saturated pores, to inhomogeneous solid frame materials, and to viscous losses due to localized ow e ects are summarized. The prospects for a comprehensive theory of wave propagation in partially saturated porous media and the reasons for needing such a theory are also discussed. The main re...
متن کاملModeling colloid attachment, straining, and exclusion in saturated porous media.
A conceptual model for colloid transport is developed that accounts for colloid attachment straining, and exclusion. Colloid attachment and detachment is modeled using first-order rate expressions, whereas straining is described using an irreversible first-order straining term that is depth dependent. Exclusion is modeled by adjusting transport parameters for colloid-accessible pore space. Fitt...
متن کاملSolute transport during cyclic flow in saturated porous media
We consider materials with large pores interconnected by thin long channels saturated with an incompressible fluid. In the absence of fluid flow, solute transport in the porous network is diffusion controlled, however, solute transport can be enhanced when the porous network is subjected to a cyclic flow with zero time average velocity. We develop a mathematical model to analyze this physical p...
متن کاملAxi-Symmetric Deformation Due to Various Sources in Saturated Porous Media with Incompressible Fluid
The general solution of equations of saturated porous media with incompressible fluid for two dimensional axi-symmetric problem is obtained in the transformed domain. The Laplace and Hankel transforms have been used to investigate the problem. As an application of the approach concentrated source and source over circular region have been taken to show the utility of the approach. The transforme...
