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…
Thermo-viscous instability of flow in a weakly heat-conducting channel
Federico Lanza, Gaute Linga, Fabian Barras +1
An instability may arise when a hot viscous fluid enters a thin gap and cools through heat transfer to a colder surrounding environment. Fluids whose viscosity increases strongly u…
Heat and super-diffusive melting fronts in unsaturated porous media
Eirik G. Flekkøy, Erika Eiser, Alex Hansen
When water is present in a medium with pore sizes in a range around 10nm the corresponding freezing point depression will cause long range broadening of a melting front. Describing…
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…
Confined colloidal droplets dry to form circular mazes
Ilaria Beechey-Newman, Natalya Kizilova, Andreas Andersen Hennig +2
During drying, particle-laden sessile droplets will leave so-called coffee-stain rings behind. This phenomenon is well-known and well-understood (Deegan et al., Nature 389, 827-829…
