WebRecent studies show that the rising of these complex fingered structures can be controlled by properly adjusting the injection rate, and the time-dependent gap width. We investigate the effectiveness of these control strategies assuming that the fluids involved are miscible. WebWe present a comparative study of the onset and propagation dynamics of the fingering phenomenon in uniform porous media with a radial configuration. With the help of the Finite Element Method (FEM)-based 2D simulations and image processing techniques, we investigate finger morphology, growth rate, interfacial length, finger length and the …

WebMay 25, 2024 · Miscible viscous fingering in radial flows is of practical relevance, as this may occur around injection wells in CO \(_2\) storage schemes and during miscible gas injection for enhanced oil recovery. The fingering behaviors are more complex than in linear flows because the flow velocity decreases with distance from the injection point.

WebWe investigate the stability of radial viscous fingering (VF) in miscible fluids. We show that the instability is decided by an interplay between advection and diffusion during initial stages of flow.
