Unstable Drainage Dynamics During Multiphase Flow Across Capillary Heterogeneities

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We use novel, fast 4D Synchrotron X‐ray imaging with large field‐of‐view to reveal pore‐ and macro‐scale drainage dynamics during gas–brine flow through a layered sandstone rock sample. We show that a single centimeter‐scale layer, similar in pore size distribution to the surrounding rock but with reduced connectivity, temporarily inhibits ...

Rapid Steam‐Assisted Temperature Swing Adsorption for Direct Air Capture Using a Rotary Adsorber

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study presents a direct air capture (DAC) device based on a steam‐regeneration rotary adsorber for high‐purity CO2. Testing of the prototype demonstrates its capability for continuous and stable carbon capture with the potential to achieve ton‐scale.

Working Principle Simulations of a Dynamic ResonantWall Shear Stress Sensor Concept

Sensors, 2008
This paper discusses a novel dynamic resonant wall shear stress sensor concept based on an oscillating sensor operating near resonance. The interaction between the oscillating sensor surface and the fluid above it is modelled using the unsteady laminar ...

Verification of a Fluid–Structure Interaction Model for Aortic Stenosis Through Comparison With In Vitro Experiments

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
A patient‐specific Fluid–structure Interaction (FSI) model of aortic stenosis was verified against in vitro experiments using a mock‐loop circulatory system with patient‐specific calcified and non‐calcified valve models under varying flow conditions. The in vitro experiments were replicated in the FSI model.

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Hydrodynamic Modelling of Flexible Woody Vegetation With Delft3D FM: Implementing Physically‐Based 2D Flow–Vegetation Interaction Processes

Hydrological Processes, Volume 40, Issue 4, April 2026.
We developed and made accessible to end‐users a numerical 2D hydrodynamic modelling approach with several advantages: reliable applicability to flexible woody vegetation from emergent to submerged conditions, and improved estimates of effective bed shear stress for sediment transport. Novelties compared to existing numerical models include a physically

Harbor‐Induced Tidal Salinity Dispersion in Partially Stratified Estuaries

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The contribution of tidal trapping to salt dispersion has been well described for well‐mixed estuaries, in terms of barotropic filling and emptying of the traps. How traps contribute to salt dispersion in deeper, partially stratified systems remains underexplored.

Hall Effects on Unsteady Hydromagnetic Flow Past an Accelerated Porous Plate in a Rotating System

Journal of Applied Fluid Mechanics, 2015
An unsteady hydromagnetic flow of a viscous incompressible electrically conducting fluid past an accelerated porous flat plate in the presence of a uniform transverse magnetic field in a rotating system taking the Hall effects into account have been ...

Testing Nodal Point Relations by Tracking Sediment Through a Bifurcation on the Jefferson River, MT, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract River bifurcations control water and sediment distribution in fluvial systems, but the physical mechanisms governing sediment partitioning remain poorly validated in natural rivers. We present a comprehensive field test of nodal point relations using radio frequency identification (RFID) tracking of 376 gravel clasts through a meandering river
