DOI: 10.1002/aic.15840
Abstract: As is known, Darcy's model for fluid flows in isotropic homogeneous porous media gives rise to singularities in the velocity field for essentially two-dimensional flow configuration, like flows over corners. Considering this problem from the… read more here.

DOI: 10.1007/s00205-020-01595-3
Abstract: We introduce a novel variant of the JKO scheme to approximate Darcy's law with a pressure dependent source term. By introducing a new variable that implicitly controls the source term, our scheme is still able… read more here.

DOI: 10.1103/physrevlett.124.187801
Abstract: We study the dynamics of a contractile active nematic fluid subjected to a Poiseuille flow. In a quasi-1D geometry, we find that the linear rheology of this material is reminiscent of Darcy's law in complex… read more here.
