Simultaneous flow of two fluid phases in a porous medium will after a transient state often lead to a steady state regime where all measurable quantities have a well defined statistical distribution with well defined averages. Experiments on horizontal quasi 2D systems have been performed in the past in our group. The goal of this project is to investigate the influence of buoyancy effects by changing the gravitational constant in the direction of the flow. This will be done by systematically tilting the models. The goal is to measure the fluid saturation and the distribution of trapped fluid clusters, the pressure drop across the model, and the dynamics linked to snap-off, coalescence and migration of clusters. The experimental data and observation will be then used for further development of the PoreLab devised theoretical model. The project is also of great technological interest for fluid flow in oil and water reservoirs and for CO2 sequestration in porous media.
