چکیده

En este trabajo se estudia un modelo de flujo bifásico (agua-aceite) en un medio poroso homogéneo considerando un desplazamiento inmiscible e incompresible. Este modelo se resuelve numéricamente usando el Método de Volumen Finito (FVM) y se comparan cuatro esquemas numéricos para la aproximación de los flujos en las caras de los volúmenes discretos. Se describe brevemente cómo obtener los modelos matemático y computacional aplicando la formulación axiomática y programación genérica. También, implementa dos estrategias de paralelización para reducir el tiempo de ejecución. Se utilizan arquitecturas de memoria distribuida (clusters de CPUs) y memoria compartida (Tarjetas gráficas GPUs). Finalmente se realiza una comparación del desempeño de estas dos arquitecturas junto con un análisis de los cuatro esquemas numéricos para un patrón de flujo de inyección de agua, con un pozo inyector y cuatro pozos productores (five-spot pattern).

Comparison 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. ...

Numerical Simulation and Estimation of the Transvers Macrodispersivity Coefficient of Aqueous Phase (Miscible) Contaminants of Salt Water in a Heterogeneous and Homogeneous Porous Media

Deterioration of groundwater resources in coastal regions due to the progression of saline water in aquifers in these regions is currently one of the important issues in providing water needs in these areas. In coastal regions, saline water enters the aquifer from below in shape of wedge. Due to the difference in the density between fresh and salty water, an interface zone forms between two flu...

A Hybridized Crouziex-Raviart Nonconforming Finite Element and Discontinuous Galerkin Method for a Two-Phase Flow in the Porous Media

In this study, we present a numerical solution for the two-phase incompressible flow in the porous media under isothermal condition using a hybrid of the linear lower-order nonconforming finite element and the interior penalty discontinuous Galerkin (DG) method. This hybridization is developed for the first time in the two-phase modeling and considered as the main novelty of this research.The p...

Investigation of pore-scale random porous media using lattice boltzmann method

The permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the Lattice Boltzmann method (LBM). Effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. Two major models of random porous media were reconstructed by computerized tomography method: Randomly distributed rectangular obstacles in a uni...

Parametric Study on Wave Interaction with a Porous Submerged Rubble Mound Breakwater Using Modified N-S Equations and Cut-Cell Method

In this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in Fortran. The code was established by combining porous flow and a two-phase model using VOF method. Modified Navier-Stokes and k-ε equations implemented to the model to simulate the flow in porous media. Cut cell method was modified to simulate...
