Control of radial miscible viscous fingering
WebViscous fingering is a commonly observed interfacial instability during fluid displacement, where a finger-like shape is formed at the fluid interface when a more viscous fluid is displaced by a less viscous fluid. In this study, a hybrid numerical model based on the lattice Boltzmann method (LBM) and finite difference method (FDM) is developed for … WebWe investigate the stability of radial viscous fingering (VF) in miscible fluids. We show that the instability is determined by an interplay between advection and diffusion during …

WebMay 3, 2024 · In this paper, the effect of channeling on viscous fingering instability of miscible displacement in porous media is studied. In fact, channeling is introduced as a solution to stabilize the viscous fingering instability. WebOct 1, 2024 · The authors found that the viscous fingering was enhanced in shear thickening fluid. They also suggested that the lattice Boltzmann method is an effective method for immiscible Non-Newtonian displacement. Displacing of Newtonian fluid by a shear thinning fluid in the heterogeneous porous media were studied by Shokri et al. [35].

Such flow instabilities are of … WebFeb 10, 2024 · Viscous fingering (VF) is a hydrodynamic interfacial instability that is inherently evolved at the interface of two fluids when a low-viscous fluid displaces another more viscous fluid in the porous medium or Hele-Shaw cell [ 1 – 3 ]. These two fluids may be miscible or immiscible.
