Consistent Velocity Approximation for FiniteVolume or Element Discretizations of DensityDriven Flow in Porous Media
Many controversial numerical simulations of density driven ow problems presented in di erent papers suggest the necessity of careful and proper design of discretization. One of the possible numerical artifact that appears if standard nite element or nite volume methods are formally applied, is the presence of arti cial numerical velocities even for the case of hydrostatic conditions. This subje...
متن کاملA New Approach for Constructing Pore Network Model of Two Phase Flow in Porous Media
Development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. In this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. Af...
متن کاملA “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media
In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...
متن کاملA 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...
متن کاملA Numerical Algorithm for Fluid Flow in 3D Naturally Fractured Porous Media
Fluid ow in three-dimensional (3D) fractured porous media is considered. The governing system of partial di erential equations consists of two subsystems { one describing the ow in the fractures, and the other describing the ow in the matrix blocks. In this paper, we develop an e cient algorithm for the numerical solution of the problem. An operator splitting technique is employed, as a part of...
