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.

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

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...

We are pleased to announce the open call for the GACM Award for the Best Ph.D. Thesis 2023! As in the last years, the GACM Executive Council would like to emphasize the importance of this call for young researchers in computational mechanics in Germany. Please consider nominating excellent young researchers for this award or encourage them to apply. A candidate automatically enters the selection procedure for the upcoming ECCOMAS Best Ph.D. award (» https://www.eccomas.org/awards/phd-awards/). Thus, a single nomination/application is sufficient to enter the selection procedure for both awards!

We assess experimentally the scaling laws that characterize the mixing region produced by the Rayleigh-Taylor instability in a confined porous medium. In particular, we wish to assess...

Strong Rayleigh–Darcy convection regime in three-dimensional porous media - Volume 943

Capturing and storing carbon dioxide (CO2), at large depths, is one of the options for reducing the amount of CO2 in our atmosphere. Although there are places on earth that have a long history with this, knowledge is lacking about how the stored gas, as a ‘supercritical fluid’, behaves at depths of…

The Nobel Prize in Physics 2021 was awarded "for groundbreaking contributions to our understanding of complex systems" with one half jointly to Syukuro Manabe and Klaus Hasselmann "for the physical modelling of Earth's climate, quantifying variability and reliably predicting global warming" and the other half to Giorgio Parisi "for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales." The Nobel Prize in Physics was announced at the Royal Swedish Academy of Sciences in Stockholm. #nobelprize

Long non-axisymmetric fibres in turbulent channel flow - Volume 916

This is the official youtube channel of the Institute of Fluid Mechanics and Heat Transfer, TU Wien. We use this broadcasting opportunity to share our latest experimental and numerical research activities. Website of the institute: http://www.fluid.tuwien.ac.at

The first box from left refers to the real recording images of the experiment and shows KMnO4 finger dissolution in water. The contour of concentration and corresponding velocity streamlines are presented in the second box from left. By using stream function, velocity components in the horizontal (u) and vertical (w) directions are derived and shown as well.

How non-Darcy effects influence scaling laws in Hele-Shaw convection experiments - Volume 892

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.
