As such, the research, although very active, can only be referred to as being in its beginning stage (Olson, ). A summary of its recent applications to flows through porous media, shallow water circulation, and two-dimensional viscous flows had been presented by Connor and Brebbia ().

A hydromechanical model with explicit fracture flow is presented for the fully coupled analysis of flow and deformation in fractured porous media.

Extended finite-element method (XFEM) was utilized to model the fracture discontinuity in the two-dimensional plane-strain mechanical by: @article{osti_, title = {Simulation of two-dimensional waterflooding using mixed finite elements}, author = {Chavent, G and Jaffre, J and Cohen, G and Dupuy, M and Dieste, I}, abstractNote = {A new method for the simulation of incompressible diphasic flows in two dimensions is presented, the distinctive features of which are: (1) reformation of the basic.

This paper presents the formulation of a three-dimensional finite element model designed to simulate ground-water flow and contaminant transport in complex multi-layered aquifer systems.

The model combines the use of two-dimensional basis functions in the x-y plane and one-dimensional basis functions in the by: 5. A two-grid block-centered finite difference method is proposed for solving the two-dimensional Darcy--Forchheimer model describing non-Darcy flow in porous media.

To construct the two-grid method we modify the original nonlinear elliptic operator of Darcy--Forchheimer flow to a twice continuously differentiable one by introducing a small and Cited by: This paper proposes a numerical model for the fluid flow in fractured porous media with the extended finite element method.

The governing equations account for the fluid flow in the porous medium. In this study, a water balance model incorporating a two-dimensional finite element groundwater flow model of the saturated-unsaturated zone is presented.

This model takes into consideration different hydrologie parameters such as rainfall, soil evaporation, crop transpiration, inter­ ception, infiltration, depression storage, and surface runoff. This report documents a two-dimensional finite element model, SAMFT2D, developed to simulate single-phase and multiphase fluid flow and solute transport in variably saturated porous media.

The formulations of the governing equations and the numerical procedures used in the code for single-phase and multiphase flow and transport are presented. An introductory textbook covering the fundamentals of linear finite element analysis (FEA) This book constitutes the first volume in a two-volume set that introduces readers to the theoretical foundations and the implementation of the finite element method (FEM).

The first volume focuses on the use of the method for linear problems. A general procedure is presented for the finite element. We construct coarse grid approximation using Generalized Multiscale Finite Element method (GMsFEM). In this method, we solve local spectral problems for construction to the multiscale basis functions for pressure and displacements.

We present numerical results for two - dimensional model problem. A coupled hygromechanical model for finite-element analyses of structures made of cementitious materials such as concrete or plaster is formulated within the framework of thermomechanics of partially saturated porous media.

In this paper the development of a two‐dimensional elastic‐absorption finite element model of isotropic elastic porous noise control materials is described. A method for coupling elastic‐absorption finite elements with conventional acoustic finite elements is also presented for the cases when the interface between the adjacent air space and the foam is either.

NAME modfe - Modular finite-element model for areal and axisymmetric ground-water flow problems ABSTRACT This MODular, Finite-Element digital-computer program (MODFE) was developed to provide solutions to ground-water-flow problems based on the governing equations that describe two-dimensional and axisymmetric-radial flow in porous media.

Publisher Summary. This chapter presents an introduction to the mathematics of the finite element method. The finite element method is a very successful application of classical methods, such as (1) the Ritz method, (2) the Galerkin method, and (3) the least squares method, for approximating the solutions of boundary value problems arising in the theory of elliptic.

Thus, most of this class is de-voted to the study of single-phase (water), uniform-density flow moving through non-deforming porous media (e.g., groundwater aquifers that are not.

As the hot pyrolysis gas travels inside the porous ablator, it carries a great deal of energy, which enhances the solid temperature in the downstream region.

Also, blowing the gas into the freestream has reduced the net convective heat flux, resulted in a decrease in the heat penetration area inside the ablator and char depth in the vicinity of.Get this from a library!
