  • Control of radial miscible viscous fingering 
    Sharma, V.; Nand, S.; Pramanik, S.; Chen, C. Y.; Mishra, M. (2021-08-28)
    We 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 the initial stages of flow. Using linear ...
  • Effect of Hele–Shaw cell gap on radial viscous fingering 
    Nand, S.; Sharma, V.; Das, S.K.; Padhee, S.S.; Mishra, M. (2022-11-21)
    The flow through a Hele–Shaw cell is an experimental prototype to study the flow through a porous medium as well as the flow in microfluidic devices. In context with porous medium flows, it is used to visualize and understand ...
  • Experimental and computational investigations to regulate the interfacial instabilities in confined geometries 
    Nand, S. (2023-02-10)
    Fingering instabilities are ubiquitous in porous media flows like enhanced oil recovery, contaminant transport in aquifers to name a few. Fingering instabilities are observed when the fluid-fluid interface deforms into ...
