Dynamic multiphase flow triggers chaotic mixing in porous media
Gaute Linga, Kevin Pierce, Marcel Moura +3
Solute mixing plays a pivotal role in a broad spectrum of chemical and biological processes across natural and engineered porous media. However, current understanding of mixing dyn…
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…
Interface instability of two-phase flow in a three-dimensional porous medium
Joachim Falck Brodin, Kevin Pierce, Paula Reis +4
We present an experimental study of immiscible, two-phase fluid flow through a three-dimensional porous medium consisting of randomly-packed, monodisperse glass spheres. Our experi…
