Particle dynamics in sheared granular matter [PDF]

, 2000
The particle dynamics and shear forces of granular matter in a Couette geometry are determined experimentally. The normalized tangential velocity $V(y)$ declines strongly with distance $y$ from the moving wall, independent of the shear rate and of the ...

Hybrid RANS/LES of plane impinging jets with k-omega based models [PDF]

, 2010
Plane impinging jets with nozzle-plate distances H/B=10 at Re=13500 and H/B=9.2 at Re=20000 are simulated with k-omega based hybrid RANS/LES models. Three ways of substitution of the turbulent length scale by the local grid size in the LES mode of the ...

Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

Advanced Functional Materials, EarlyView.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.
