POROMULT: Multiscale computational poromechanics (10112)

Project nummer: 10112

Omschrijving van het onderzoek

This project involves two mutually converging research lines:
The first research line is the generalization of a recently developed two-dimensional multi-scale model for fluid flow in fracturing, porous media to a general three-dimensional numerical model. Level sets are necessary to keep track of the crack front in 3D. Modes like fingering and complex, curved crack fronts are considered. Essentially, this is a bifurcation problem, and eigenvalue and perturbation techniques may be necessary as part of the multi-scale solution strategy. The other research line departs from the same starting point and is a combination of theoretical, numerical and experimental investigations into an accurate constitutive model of crack propagation in saturated swelling porous media. The project will zoom into what happens precisely at the crack tip that causes propagation of the crack in a fluid-saturated medium. The crack propagation criterion will be introduced into the 3D model developed in the first research line of the project and 3D simulations will be run to at least reproduce the trends in the 3D experiments. The utilisation of the results will concentrate on two fields: Petroleum and Biomedical engineering. Instability of deviated bore holes, hydraulic fracturing, CO2 sequestration and intervertebral disc herniation are focussed applications.
