Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Ultra-stripped supernovae and double neutron star systems

, 2015
The evolution of close-orbit progenitor binaries of double neutron star (DNS) systems leads to supernova (SN) explosions of ultra-stripped stars. The amount of SN ejecta mass is very limited from such, more or less, naked metal cores with envelope masses

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

The effect of upstream disturbance on the angle of sound emission in a supersonic round jet

Journal of Fluid Science and Technology, 2014
The three-dimensional time-dependent compressible Navier-Stokes equations are numerically solved to study acoustic emission mechanisms in a supersonic round jet at high convective Mach numbers. A 5th-order compact upwind algorithm developed by Deng et al.

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

Vietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

DNS study on the development of boundary layer with heat transfer under the effects of external and internal disturbances

Journal of Fluid Science and Technology, 2014
The effects of external and internal disturbances on the development of boundary layer with heat transfer are investigated by means of direct numerical simulation (DNS) based on the finite difference scheme.

Direct Numerical Simulation of Acoustic Disturbances in the Rectangular Test Section of a Hypersonic Wind Tunnel [PDF]

Direct numerical simulations (DNS) of the full-scale rectangular nozzle of a hypersonic wind tunnel are conducted to study the acoustic freestream fluctuations radiating from turbulent boundary layers (TBLs) along the nozzle walls.

Below‐ground drivers of rhizosphere functional gene assembly during Moso bamboo expansion

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Moso bamboo (Phyllostachys edulis) expansion threatens subtropical forest biodiversity, yet how intraspecific root trait variation shapes rhizosphere microbial functional potential remains unclear.
