Job displacement costs of phasing out coal
Journal of Public Economics, 2022 The reduction of carbon emissions will require a rapid phasing out of coal and the displacement of millions of coal miners. How much could this energy transition cost mining workers? We use the dramatic collapse of the UK coal industry to estimate the long-term impact on displaced miners.

Influence of wall roughness on two-phase displacement
Shenzhen Daxue xuebao. Ligong ban, 2022 In the development of oil and gas fields, water flooding is still the most important development method. The influence of the existence of rough channel on two-phase flow cannot be ignored.

Full surface strain measurement using shearography [PDF]
, 2001 Shearography is a full-field optical technique usually used for the determination of surface strain. Correlation of interferometric speckle patterns recorded before and after the object deformation yields fringes sensitive to displacement gradient ...

Displacement Convexity and Minimal Fronts at Phase Boundaries [PDF]
Archive for Rational Mechanics and Analysis, 2008 We show that certain free energy functionals that are not convex with respect to the usual convex structure on their domain of definition, are strictly convex in the sense of displacement convexity under a natural change of variables. We use this to show that in certain cases, the only critical points of these functionals are minimizers.

Impact of Pore-Scale Characteristics on Immiscible Fluid Displacement
Geofluids, 2020 Immiscible fluid flows (drainage displacement) where nonwetting fluid invades porous media filled with wetting fluid are frequently observed. Numerous studies have confirmed the existence of three different displacement patterns which depend on the ...

A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]
, 2012 Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.
