🚨 PAPER ALERT 🚨 Can we predict the #dispersion of contaminants in #groundwater flows? 🧵 1/n Here marcodepaoli.com/2025/10/01/d... we provide an example. Movie: Evolution of a Rayleigh-Taylor system in porous media with dispersion and buoyancy.

🚨 new paper alert 🚨 1/3 🌊 Measuring experimentally the dispersion of #microplastic #fibres in turbulent flows is incredibly challenging, due to their small size. However, experiments are key to develop reliable models to predict the fate of microplastics in #environmental #flows.

Computer simulations indicate that CO2 can be stored underground indefinitely by dissolving in groundwater, forming a denser liquid that sinks, ensuring long-term storage under suitable geological conditions. doi.org/g9dtm4

Computer simulations suggest CO₂ can be stored underground indefinitely

We have to stop emitting carbon dioxide (CO2) if we want to save the climate—there is no doubt about that. But that alone will not be enough.

Lässt sich CO2 dauerhaft im Boden speichern? Ja, sagt eine neue Modellrechnung der TU Wien, die genau analysiert, wie sich CO2-haltiges Wasser im Boden verhält. www.tuwien.at/tu-wien/aktu...

Was passiert, wenn man abgeschiedenes CO2 in den Boden pumpt? Hochaufwändige Computersimulationen ermöglichen es nun, das langfristige Verhalten vorherzusagen.

🧵1/8 To mitigate the catastrophic effects of #globalwarming, we will have to capture from the atmosphere billions of tons of #carbondioxide, and store it underground. And there is no doubt about that. But what will it happen in the subsurface? agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Simulation and Modeling of Convective Mixing of Carbon Dioxide in Geological Formations

Convective mixing of carbon dioxide in geological formations follows different regimes During a regime in which the flux is constant, mixing in 3D simulations is 13% larger than in 2D simulations...

One possible solution to the problem of global warming is represented by the carbon capture and storage (CCS) process. CCS consists of three phases: carbon dioxide produced from localised sources (e.g., power or industrial plants) is captured, pressurised to reach a liquid state,

Universal behavior of scalar dissipation rate in confined porous media

Gravity-driven Rayleigh-Taylor convective dissolution in porous media is controlled by buoyancy and diffusion. We show that the main features of the mixing dynamics of dissolution exhibits a superlinear scaling that is universal.
