Electro-osmotic flow and mixing in heterogeneous microchannels.
Analytical and numerical studies of secondary electro-osmotic flow (EOF) and its mixing in microchannels with heterogeneous zeta potentials are carried out in the present work. The secondary EOFs are analyzed by solving the Stokes equation with heterogeneous slip velocity boundary conditions. The analytical results obtained are compared with the direct numerical simulation of the Navier-Stokes ...
متن کاملTransient Fluid Flow in Heterogeneous Porous Media
A stable Alternating Direction Implicit finite-difference algorithm is used to model transient fiuid flow in heterogeneous porous media. In connection with the laboratory system for pressure transient testing of core permeability, the effects of permeability heterogeneities on the characteristics of the pressure transient were investigated. The results show that the early portion of the pressur...
متن کاملNumerical Simulation of Three-Phase Flow in Heterogeneous Porous Media
We describe an efficient numerical simulator, based on an operator splitting technique, for three-phase flow in heterogeneous porous media that takes into account capillary forces, general relations for the relative permeability functions and variable porosity and permeability fields. Our numerical procedure combines a non-oscillatory, second order, conservative central difference scheme for th...

متن کاملModeling Fluid Flow in Heterogeneous and Anisotropic Porous Media
Permeability distribution in reservoirs is very important for the flow ofwater or oil and gas. In this study, the effects of various heterogeneous permeability distributions on the flow field are simulated using the finite difference technique. We have simulated the flow for two types of heterogeneous distributions, one is Gaussian and the other is self-similar or fractal, the latter being much...
