Towards a robust CFD model for aeration tanks for sewage treatment – a lab-scale study

Engineering Applications of Computational Fluid Mechanics, 2017
Detailed insight into the hydrodynamics of aeration tanks is of crucial importance for improvements in treatment efficiency, optimization of the process design and energy-efficient operation. These factors have triggered increasing interest in the use of

Turbulence Modeling Insights into Supercritical Nitrogen Mixing Layers

Energies, 2020
In Liquid Rocket Engines, higher combustion efficiencies come at the cost of the propellants exceeding their critical point conditions and entering the supercritical domain.

Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers

Advanced Science, EarlyView.
Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

Influence of atmospheric vertical wind and turbulence on noctilucent clouds

Frontiers in Astronomy and Space Sciences
Noctilucent clouds (NLCs), also called Polar Mesospheric Clouds (PMC), are high-altitude ice clouds in the summer mesopause region, mainly at polar latitudes.

AI‐Assisted Engineering of Glycyrrhizic Acid/Simvastatin Nanocrystals for Multifunctional Treatment of Bacterial Osteomyelitis

Advanced Science, EarlyView.
Through AI‐assisted screening from FDA‐approved API to overcome the limitations of bacterial osteomyelitis treatment, glycyrrhizic acid and simvastatin are identified as a multifunctional combination capable of self‐assembling into mechanism‐targeting nanocrystals that effectively neutralize reactive oxygen species, suppress M1 macrophage polarization,

First Kinetic 3‐D Simulations of the High‐Latitude Electrojet Spanning an Entire Turbulent Flux Tube

Geophysical Research Letters
Radar and rocket observations of the terrestrial ionosphere frequently measure turbulent plasma waves, especially during geospace storms. The non‐linear behavior of these waves remains poorly characterized. This paper presents the first fully kinetic 3‐D

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

Advanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...

Modelling of transport in homogeneous turbulence

Modélisation du transport en turbulence homogène La modélisation est essentielle pour comprendre et reproduire les phénomènes physiques dominants ayant lieu dans des écoulements turbulents naturels (atmosphériques, océaniques). En effet, la dynamique des écoulements géophysiques résulte d'interactions complexes à des échelles et ...

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Performance characterization of a laminar gas inlet [PDF]

Atmospheric Measurement Techniques
Aircraft-based measurements enable large-scale characterization of gas-phase atmospheric composition, but these measurements are complicated by the challenges of sampling from high-speed flow.
