This paper presents the application of parallel computing techniques to large-scale modeling of fluid flow in the unsaturated zone (UZ) at Yucca Mountain, Nevada. In this study, parallel computing techniques, as implemented into the TOUGH2 code, are applied in large-scale numerical simulations on a distributed-memory parallel computer. The modeling study has been conducted using an over-1-milli...

The past decades have witnessed an increasing interest in numerical simulation for flow fractured porous media. To date, most studies focused on 2D or pseudo-3D computational models, where the impact of 3D complex structures seepage has not been fully addressed. This work presents a method modeling heterogeneous structures, typically stochastic discrete fractures and inclusions, are able to be ...

The purpose of this work is to study the effect of oscillatory MHD blood flow in stenosed artery. The analytical and numerical results are obtained for oscillatory MHD blood flow, which is assumed to be a Newtonian fluid. It was also assumed that the surface roughness is of cosine shaped and the maximum height of roughness is negligible, compared with the radius of un-constricted tube. The flui...

in this paper a novel numerical approach is presented for solving the transient incompressible fluid flow problems with free surfaces in generalized two-dimensional curvilinear coordinate systems. solution algorithm is a combination of implicit real-time steps and explicit pseudo-time steps. governing fluid flow equations are discretized using a collocated finite-volume mesh. convective terms a...

Geophysical methods can be used to create images of the Earth’s interior that constitute snapshots at the moment of data acquisition. In many applications, it is important to measure the temporal change in the subsurface, because the change is associated with deformation, fluid flow, temperature changes, or changes in material properties. We present an overview of how noninvasive geophysical me...

in this paper, direct numerical simulation of two-phase incompressible gas-liquid flow for simulation of bubble motion in a microtube is presented. microtube radius is 10 µm. the interface is tracked using volume of fluid (vof) method with continuous surface force (csf) model. the flow is solved using a finite volume scheme, based on piso algorithm. numerical simulation is performed on a axisym...

A coupled multiphase fluid flow and discrete fracturing model is applied to simulate bench-scale gas migration experiments on compacted bentonite. The numerical modeling based the linking of simulator TOUGH2 with a Rigid-Body-Spring Network model, which enables (lattice) representation elasticity individual fractures. evolution complex network dilatant paths modeled through opening breakage lat...

In this paper conjugated heat transfer in thermal entrance region through the sinusoidal wavy channel has been investigated. The fluid flow is assumed to be laminar, steady state, incompressible, and hydrodynamically fully developed. A constant heat flux is assumed to be applied on the outer edge of the channel wall. In this study the governing equations including continuity, momentum and energ...

ABSTRACT Modeling of fluid flow and solute transport through fractured rock is an important component of engineering analysis in many disciplines including groundwater contamination, nuclear waste disposal, petroleum and gas production, mine excavation and geothermal production. Several studies have been conducted on single rock fracture using parallel plate model. An attempt has been made to s...
