Flow morphology and patterns in porous media convection: A persistent homology analysis
Marco De Paoli, Sergio Pirozzoli, Catherin Neena Lalu +1
Convective mixing in porous media is crucial in both geophysical and industrial fields, spanning applications ranging from carbon dioxide sequestration to geothermal energy extract…
Solute mixing in porous media with dispersion and buoyancy
Marco De Paoli, Guru Sreevanshu Yerragolam, Roberto Verzicco +1
We analyse the process of convective mixing in two-dimensional, homogeneous and isotropic porous media with dispersion. We considered a Rayleigh-Taylor instability in which the pre…
Full rotational dynamics of plastic microfibers in turbulence
Vlad Giurgiu, Giuseppe Carlo Alp Caridi, Marco De Paoli +1
The motion, settling, and dispersion of microplastics in the ocean are determined by their rotational dynamics. We present experiments on elongated, large aspect ratio, and mildly…
Towards the understanding of convective dissolution in confined porous media: thin bead pack experiments, two-dimensional direct numerical simulations and physical models
Marco De Paoli, Christopher J. Howland, Roberto Verzicco +1
We consider the process of convective dissolution in homogeneous and isotropic porous media. The flow is unstable due to the presence of a solute that induces a density difference…
Transport scaling in porous media convection
Xiaojue Zhu, Yifeng Fu, Marco De Paoli
We present a theory to describe the Nusselt number (), corresponding to the heat or mass flux, as a function of the Rayleigh--Darcy number (), the ratio of buoyant driving…
