The Pisacano Leadership Foundation, the philanthropic arm of the American Board of Family Medicine, recently selected its 2014 Pisacano Scholars. These 7 medical students follow in the footsteps of 95 scholar alumni who are practicing physicians and 16 current scholars who are enrolled in medical schools or family medicine residency programs across the country. The Pisacano Leadership Foundatio...

A Darcy law for evolving microstructure is derived by homogenisation of Stokes flow. We transform the equations from locally domain onto a periodic reference domain. There, we pass to limit employing method two-scale convergence. After transforming back its original domain, obtain Law microstructure. This does not only capture space- and time-dependent permeability, but also includes how change...

We propose and analyze a hybrid discontinuous Galerkin method for the solution 10 of incompressible flow problems, which allows to deal with pure Stokes, pure Darcy, and 11 coupled Darcy-Stokes flow in a unified manner. The flexibility of the method is demonstrated 12 in numerical examples.

Due to the long-term fluid-solid interactions in waterflooding, the tremendous variation of oil reservoir formation parameters will lead to the widespread evolution of preferential flow paths, thereby preventing the further enhancement of recovery efficiency because of unstable fingering and premature breakthrough. To improve oil recovery, the characterization of preferential flow paths is esse...

The Darcy model is based on a plethora of assumptions. One of the most important assumptions is that the Darcy model assumes the drag coefficient to be constant. However, there is irrefutable experimental evidence that viscosities of organic liquids and carbon-dioxide depend on the pressure. Experiments have also shown that the drag varies nonlinearly with respect to the velocity at high flow r...

Water alternating gas (WAG) technique is used in the petroleum industry to inject carbon dioxide (CO2) into underground formations either for sequestration or enhanced oil recovery (EOR) processes. CO2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. Modeling and investigating effects of CO...
