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…

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…
