Adaptive Mesh Reenement for Single and Two Phase Ow Problems in Porous Media
نویسنده
چکیده
abstract This paper is devoted to the study of a posteriori error estimates and adaptive methods for a mixed nite element-nite volume approximation for single and two phase ow problems in porous media. In a rst step we analyze a scalar nonlinear convection diiusion equation and give a rigorous a posteriori error estimate for the Cauchy problem. In a second step these results are used to implement an adaptive method for the systems of density driven ow and two phase ow in porous media.

متن کاملMultiscale Multiphysic Mixed Geomechanical Model for Deformable Porous Media Considering the Effects of Surrounding Area
Porous media of hydro-carbon reservoirs is influenced from several scales. Effective scales of fluid phases and solid phase are different. To reduce calculations in simulating porous hydro-carbon reservoirs, each physical phenomenon should be assisted in the range of its effective scale. The simulating with fine scale in a multiple physics hydro-carbon media exceeds the current computational ca...
متن کاملAdaptive Mesh Re nement and Multilevel Iteration for Flow inPorous
An adaptive local mesh re nement algorithm originally developed for unsteady gas dynamics by Berger [12, 14] is extended to incompressible ow in porous media. Multilevel iteration and domain decomposition methods are introduced to accommodate the elliptic/parabolic aspects of the ow equations. The algorithm is applied to a two-phase polymer ooding model consisting of a system of nonlinear hyper...

An interconnected set of algorithms is presented for the simulation of two-phase ow in porous media achieving more than two orders of magnitudes acceleration. The accuracy and e ciency of the approach is demonstrated through 2D and 3D numerical experiments for a range of two-phase porous media problems involving single cracks, heterogeneous permeability, and hydrophobic and hydrophilic media
متن کاملComparison of Thermal Dispersion Effects for Single and two Phase Analysis of Heat Transfer in Porous Media
The present work involves numerical simulation of a steady, incompressible forcedconvection fluid flow through a matrix of porous media between two parallel plates at constanttemperature. A Darcy model for the momentum equation was employed. The mathematical model forenergy transport was based on single phase equation model which assumes local thermal equilibriumbetween fluid and solid phases. ...
