    • Coriolis effects on fingering patterns under rotation 

      Alvarez-Lacalle, Enrique; Gadelha, Hermes; Miranda, José A. (American Physical Society, 2008-09-30)
      Article
      Accés obert
      The development of immiscible viscous fingering patterns in a rotating Hele-Shaw cell is investigated. We focus on understanding how the time evolution and the resulting morphologies are affected by the action of the ...

    • Minimization of Viscous Fluid Fingering: A Variational Scheme for Optimal Flow Rates 

      Dias, Eduardo O.; Álvarez Lacalle, Enrique; Carvalho, Marcio S.; Miranda, José A. (2012-10-05)
      Article
      Accés obert
      Conventional viscous fingering flow in radial Hele-Shaw cells employs a constant injection rate, resulting in the emergence of branched interfacial shapes. The search for mechanisms to prevent the development of these ...
