• Crack localization and the interplay between stress enhancement and thermal noise 

      Sinha, Santanu; Roy, Subhadeep; Hansen, Alex (Peer reviewed; Journal article, 2021)
      We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The thermal noise is introduced by defining a ...
    • Effective rheology of two-phase flow in a capillary fiber bundle model 

      Roy, Subhadeep; Hansen, Alex; Sinha, Santanu (Journal article; Peer reviewed, 2019)
      We investigate the effective rheology of two-phase flow in a bundle of parallel capillary tubes carrying two immiscible fluids under an external pressure drop. The diameter of the tubes vary along the length which introduce ...
    • Flow-Area Relations in Immiscible Two-Phase Flow in Porous Media 

      Roy, Subhadeep; Sinha, Santanu; Hansen, Alex (Journal article; Peer reviewed, 2020)
      We present a theoretical framework for immiscible incompressible two-phase flow in homogeneous porous media that connects the distribution of local fluid velocities to the average seepage velocities. By dividing the pore ...
