WebThe Darcy Forchheimer model used for modeling porous media allows us to simply add a porosity zone into our fluid domain without any expense. In order to use the model, you have to put a fvOptions file into the constant folder including the following content (OpenFOAM-v6): The Darcy Forchheimer acts in the momentum equation as a sink term . WebAs discussed in Section 3.2, simulation of density-driven flow in the porous media usually requires high computational demand in the training approaches to capture the rapidly evolving and nonlinear flow behaviors involved in the space–time domain.
