Query: A computational continuum model of poroelastic beds   Despite the ubiquity of fluid flows interacting with porous and elastic
materials, we lack a validated non-empirical macroscale method for
characterizing the flow over and through a poroelastic medium. We propose a
computational tool to describe such configurations by deriving and validating a
continuum model for the poroelastic bed and its interface with the above free
fluid. We show that, using stress continuity condition and slip velocity
condition at the interface, the effective model captures the effects of small
changes in the microstructure anisotropy correctly and predicts the overall
behaviour in a physically consistent and controllable manner. Moreover, we show
that the performance of the effective model is accurate by validating with
fully microscopic resolved simulations. The proposed computational tool can be
used in investigations in a wide range of fields, including mechanical
engineering, bio-engineering and geophysics.
