Abstract:
This paper attempts to study flows within fractures through a set of numerical simulations. In addition, a special care is given to hydraulic features and characteristics of fractures. The research is performed through the application of calculative fluid dynamics and a finite volume discrete schema. The investigated flows are laminar, single-phase and stable flows of water and air through fractures with penetrable walls. The selected fracture geometry is inspired from the tomographic scan of a stone fracture. Water and air are modeled in fractures with permeable walls and different permeabili

Abstract:
Summary A relationship between permeability tensor and coordinate orientation is used to estimate the error that occurs when some of the terms in the permeability tensor are neglected. The formula for calculating the errors that appear in the magnitude and direction of flow rate are presented. The results are applicable to any reservoir system that is influenced by directional permeability. Introduction Reservoir management experience has demonstrated that anisotropic permeability is needed to correctly solve fluid-flow problems in a variety of realistic settings.

Abstract:
Abstract Upstream collocation is a fast and accurate scheme for simulating multiphase flows in oil reservoirs. In contrast to standard orthogonal collocation, upstream collocation yields numerical solutions to the Buckley-Leverett problem that converge to correct solutions physically. The failure of standard orthogonal collocation is not surprising, since the Buckley-Leverett problem as commonly stated is posed incompletely. The equal-area rule of Buckley and Leverett and the Welge tangent construction both specify additional constraints needed to close the problem properly. An error analysis

Electoral systems as endogenous re-distributive institutions (Tsebelis, 1990) help to define the rules of the game. In this manner they have an important impact among regional, class, ethnic, gender, and other sub-groups of the general population on the distribution and variation in outcome of who is nominated for, and elected to, national office. In particular, there is a well-established and growing literature on the impact of electoral systems and electoral system reform on the representation of women in national legislative bodies (Darcy, Welch, and Clarke 1994; Matland and Taylor 1997; Ca

Abstract:
Summary We introduce an accurate cell-centered method for modeling Darcy flow on general quadrilateral, hexahedral, and simplicial grids. We refer to these discretizations as the multipoint-flux mixed-finite-element (MFMFE) method. The MFMFE method is locally conservative with continuous fluxes and can be viewed within a variational framework as a mixed finite-element method with special approximating spaces and quadrature rules. We study two versions of the method: with a symmetric quadrature rule on smooth grids and a nonsymmetric quadrature rule on rough grids. The framework allows for hand

Abstract:
Λ-fractional analysis has already been presented as the only fractional analysis conforming with the Differential Topology prerequisites. That is, the Leibniz rule and chain rule do not apply to other fractional derivatives; This, according to Differential Topology, makes the definition of a differential impossible for these derivatives. Therefore, this leaves Λ-fractional analysis the only analysis generating differential geometry necessary to establish the governing laws in physics and mechanics. Hence, it is most necessary to use Λ-fractional derivative and Λ-fractional transformation to de

Dynamic axial compression (DAC) columns are key elements in simulated moving bed, which is a chromatography process in drug industry and chemical engineering. In this study, rules for designing distributors are proposed based on mass conservation and validated by experiments, the computer aided design (CAD) and the computational fluid dynamics (CFD). Experimental works are conducted to choose feasible numerical parameters for simulations. In CFD, the transient laminar flow fields are governed by the momentum and species transport equations with Darcy's law to model the porous zone in the packe

The thermal instability of a couple-stress nanofluid saturated by a porous media is studied in this article. For the porous medium, the Darcy–Brinkman model is used. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis. Three cases of free-free, rigid-rigid and rigid-free boundaries are considered. For this problem, oscillatory convection is ruled out. By using the one-term Galerkin method and normal mode analysis, we solve the eigenvalue problem with Rayleigh number as an eigenvalue.

Abstract:
This chapter examines Jane Austen's competing models of human behavior that also offers important insights into strategic thinking. One competing model focuses on people's emotions, which Austen acknowledges can cause bad decisions. For example, the jealous Caroline Bingley remarks to Mr. Darcy that Elizabeth's eyes have “a sharp, shrewish look,” but this only makes him reply that Elizabeth is “one of the handsomest women of my acquaintance.” Influenced by emotion, Miss Bingley does not think her plan through and it backfires. Emotions can affect people's choices, but people can strategically

Based on the mixture theory, frost-susceptible soils are formulated to capture the Darcy flux and thermal actions below the pipelines. Constitutive models that combine the cryo-suction are presented to reproduce the changes in volume, strength, and thermal characteristics of solid grain, pore water, and ice crystal.

Abstract Fluid-flow topology optimization (FTO) allows the generation of innovative flow-channel layouts with minimal pressure drop (power dissipation) between inlet and outlet ports in a given design domain. FTO was first explored using Stokes flow with the material in the design domain modeled as a porous medium governed by Darcy’s law. More recently, Navier-Stokes flow has been implemented to consider higher Reynolds numbers. The objective of this work is to demonstrate the effect of the Reynolds number on the FTO results and generate a set of design rules. To this end, a density-based FTO

Abstract This paper presents a digital stimulation workflow intended to revolutionize the area of tedious and core-destructive acidizing experiments. To adjust acid treatment design with respect to actual geology and lithology, several acidizing tests must be performed on cores taken from the reservoir of interest. However, complications related to core sampling and experimental uncertainties often make such tests infeasible, since the adjustment is based on "equivalent" data, which inevitably affects the treatment performance.
