Pore-scale viscous fingering in porous media

WebThermal-viscous fingering instability in porous media is a common phenomenon in nature, as well as in many scientific problems and industrial applications. Despite the importance, however, thermal transport in flow of a non-Newtonian fluid in porous media and the resulting fingering has not been studied extensively, especially if the pore space is … WebSep 21, 2015 · However, there is very little pore-scale investigation on viscous fingering phenomenon in miscible displacement in porous media. As early as 1997, Rakotomalala et al. used the BGK lattice gas method to study the viscous fingering phenomenon in miscible displacement as the viscosity ratios ranged from 0.01 to 100 and Péclet numbers ranged …
