The chromium diffusion step is performed at °C for 24 h, and the microstructure of the steel is affected during the process (Fig. ).The change in the microstructure of the alloy is due to the heat treatment during the coating process. At °C for a period of time of about 24 h chromium carbides in the substrate are dissolved and, since the cooling process is slow enough, carbon. Sharp and diffuse fronts in oil reservoirs: front tracking and capillarity. Proceedings of the SEG/SIAM/SPE Conference on Mathematical and Computational Methods in Seismic Exploration and Reservoir Modeling. Abstract. Arguments are advanced that physically meaningful nonunique solutions to Riemann problems can occur. The implications of this point of view for both theory and computation are developed, as part of a review of recent progress concerning the interaction of nonlinear waves and the front tracking Cited by: 3. A fingering interface instability occurs in laboratory studies of flow oil reservoirs. The phenomenon has been captured numerically in a series of papers by the authors and co-workers.

At the initial temperature of K and pressure of bar (at the bottom of the reservoir), the mass density of water, reservoir oil and CO 2 are ∼, and g/cm 3. The dynamic evolution of tracked waves by a front-tracking algorithm may lead on either numerical or physical grounds to intersections. The correct resolution of these intersections is described locally by the solution of Riemann problems and requires a bifurcation of the topology defined by the tracked waves.

Bernaise (Binary Electrohydrodynamic Solver) is a flexible high-level finite element solver of two-phase electrohydrodynamic flow in complex geometries. Two-phase flow with electrolytes is relevant across a broad range of systems and scales, from “lab-on-a-chip” devices for medical diagnostics to enhanced oil recovery at the reservoir scale. The front-tracking (Glimm et al. ), volume-of-fluid (Hirt and Nichols ), and level-set (Osher and Sethian ) methods have been used to solve moving boundary problems for tracking or capturing sharp interfaces. The advantage of these methods is that one can perform direct numerical simulations involving surfaces using the Eulerian.   The simultaneous flow of multiple fluid phases through a porous solid occurs in many natural and industrial processes—for example, rainwater infiltrates into soil by displacing air, and carbon dioxide is stored in deep saline aquifers by displacing brine. It has been known for decades that wetting—the affinity of the solid to one of the fluids—can have a strong impact on the flow, but. Heavy oils are typically known for their high asphaltene content (> 5 wt.%), such asphaltenes [71, 72] forms viscoelastic network of large size nanoaggregate clusters and promote formation damage as a result of self-association, and if sub-saturated oil reservoirs exist at pressures above the bubble point. The asphaltene becomes excluded from.
