Abstract

This data set contains the simulation data for the results presented in S. Burbulla, M. Hörl, and C. Rohde (2022). "Flow in Porous Media with Fractures of Varying Aperture." Submitted for publication, https://doi.org/10.48550/arXiv.2207.09301. We consider the numerical solutions of single-phase fluid flow governed by Darcy's law in a fractured porous medium for four different scenarios. For each scenario, we provide the raw vtk-files (*.vtu and *.vtp) of the pressure field for different values of the fracture aperture and for discontinuous Galerkin discretizations of four different discrete fracture models and one full-dimensional reference model. These files can be reproduced by running the script main_comparison.py of the corresponding source code (see S. Burbulla, M. Hörl, C. Rohde (2022). "Source Code for: Flow in Porous Media with Fractures of Varying Aperture", https://doi.org/10.18419/darus-3012, DaRUS.). Moreover, we provide visualizations (*.pdf) of the simulation results for each scenario that can be reproduced by running the script plot_comparison.py which is part of the corresponding source code. This includes, for each value of the fracture aperture, a visualization of the full-dimensional reference pressure and velocity, as well as a plot of the effective fracture pressure and the corresponding absolute error (compared to the full-dimensional reference solution) for the different discrete models. In addition, the L2-error of the effective fracture pressure is plotted as function of the fracture aperture for the different reduced models.Scenario 1a (section-6.1.1.tar.gz): Flow perpendicular to a sinusoidal fracture with constant total aperture (two-dimensional). Scenario 1b (section-6.1.2.tar.gz): Flow perpendicular to a sinusoidal fracture with constant total aperture (three-dimensional). Scenario 2 (section-6.2.tar.gz): Flow perpendicular to an axisymmetric sinusoidal fracture (two-dimensional). Scenario 3 (section-6.3.tar.gz): Tangential flow through an axisymmetric sinusoidal fracture (two-dimensional). A detailed description of the different scenarios can be found in Section 6 in S. Burbulla, M. Hörl, and C. Rohde (2022). "Flow in Porous Media with Fractures of Varying Aperture." Submitted for publication, https://doi.org/10.48550/arXiv.2207.09301.
