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…

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…

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…
