    Porous zone in OpenFOAM

    OpenFOAM offers an easy way to solve for a single flow in systems with porous zones, with the possibility of specifying the porosity and to use Darcy-Forchheimer or power law models. This feature is very versatile, allowing the user to specify also porous zones not aligned with the main reference frame and multiple porous zones in the same case. Currently this feature is implemented in a compressible flow solver (rhoPorousSimpleFoam), with both an explicit and an implicit treatment of the momentum source term due to the presence of the porous zone. I will show the basic functionalities of this OpenFOAM feature with a simple example of a 2D channel made…
