A comparison of different image analysis techniques for mapping spatiotemporal pH and carbon dissolution in density-driven convection of CO2 in water
Yao Xu, Marcel Moura, Eirik Grude Flekkøy +1
Density-driven convection enhances the carbon dissolution rate, which is significant for the geological carbon storage. This process will also influence the spatiotemporal pH and c…
Drainage front width in a three-dimensional random porous medium under gravitational and capillary effects
Paula Reis, Knut Jørgen Måløy
A theoretical approach to estimating stable drainage front widths in three-dimensional random porous media under gravitational and capillary effects is presented. Based on the fron…
Droplet spreading in a wedge: A route to fluid rheology for power-law liquids
Marcel Moura, Vanessa Kern, Knut Jørgen Måløy +2
Measuring the rheology of liquids typically requires precise control over shear rates and stresses. Here, we describe an alternative route for predicting the characteristic feature…
Interaction between corner and bulk flows during drainage in granular porous media
Paula Reis, Gaute Linga, Marcel Moura +4
Drainage in porous media can be broken down into two main mechanisms: a primary piston-like displacement of the interfaces through the bulk of pore bodies and throats, and a second…
Mapping dissolved carbon in space and time: An experimental technique for the measurement of pH and total carbon concentration in density driven convection of CO dissolved in water
Hilmar Yngvi Birggison, Yao Xu, Marcel Moura +2
We present an experimental technique for determining the pH and the total carbon concentration when \ch{CO2} diffuses and flows in water. The technique employs three different pH i…
A simplified pore-scale model for slow drainage including film-flow effects
Paula Reis, Marcel Moura, Gaute Linga +3
Film flow through networks of corners and capillary bridges can establish connections between seemingly isolated clusters during drainage in porous media. Coupled with drainage thr…
