In a recent work, we introduced a numerical approach that combines the mixed-finite-element (MFE) and the discontinuous Galerkin (DG) methods for compositional modeling in homogeneous and heterogeneous porous media. In this work, we extend our numerical approach to 2D fractured media. We use the discrete-fracture model (crossflow equilibrium) to approximate the two-phase flow with mass transfer...

A numerical characterization of a fractured rock mass and its mechanical behavior using discontinuum approach was carried out utilizing lattice-spring-based synthetic (LS-SRM) models. First, LS-SRM models on laboratory scale were created to reproduce standard tests Triassic sandstone samples from quarry in Germany. Subsequently, the intact properties upscaled an element volume representative fo...

the effects of isothermal aging at temperatures between 550-850 ?c for durations of 1-100 h on microstructure, tensile properties, and impact fracture behavior of 316l austenitic stainless steel weld metal have been investigated. for this purpose, various techniques including metallographic observations, measurement of ferrite content using ferritscope, and fractographic investigations have bee...

Models that aim to optimize the design of supply chain networks have gained more interest in the supply chain literature. Mixed-integer linear programming and discrete-event simulation are widely used for such an optimization problem. We present a hybrid approach to support decisions for supply chain network design using a combination of analytical and discrete-event simulation models. The prop...

Discrete fracture network (DFN) is an effective means of describing the coupling heat flow in underground fractured rock mass. In this paper, improved DFN proposed by introducing correlation function trace length and aperture, which more consistent with real data. Next, based on model, influence roughness fluid transmission was evaluated, relationship between aperture joint coefficient (JRC) es...

and become focused. The focused unsaturated flow will increase relative permeability of its path, and cause flow A numerical modeling study is presented to investigate flow– further focusing. Focused flow paths exist in the unsatufocusing phenomena in a large-scale fracture network, constructed rated rock of the Yucca Mountain site. For example, using field data collected from the unsaturated z...
