Convective and absolute instabilities in non-Boussinesq mixed convection [PDF]

Theoretical and Computational Fluid Dynamics, 2007
The problem of non-Boussinesq mixed convection in a vertical channel formed by two differentially heated infinite plates is investigated and the complete convective/absolute instability boundary is computed for a wide range of physical parameters. A physical insight into the mechanisms causing instabilities is given. In particular, it is shown that the

Role of convective mixing and evaporative cooling in shallow convection

Journal of Geophysical Research: Atmospheres, 2017
AbstractLarge‐eddy simulations of shallow convection are used to evaluate the role of convective mixing and evaporative cooling in the vertical transport of mass, heat, and moisture in nonprecipitating shallow convection. Evaporative cooling is found to increase mass flux and the magnitude of heat and moisture fluxes, comparing twin large‐eddy ...

Ambient‐Spray Ni–Cu(–O)/Ag Nanowire Transparent Heaters for High‐Temperature Heating and Far‐/Near‐Field EMI Suppression

Advanced Materials Interfaces, EarlyView.
A vacuum‐free, ambient‐spray Ni–Cu(–O)/Ag nanowire transparent‐heater platform is realized via conformal junction‐shell engineering and silica–hybrid overcoating, enabling robust high‐temperature heating together with GHz‐band far‐field EMI shielding and near‐field magnetic‐noise attenuation.

Numerical Investigation of Turbulent Mixed Convection of Liquid Metal in Inclined Tube Based on Second-order Differential Heat Flux Model

Yuanzineng kexue jishu
Liquid metal reactors, widely used in advanced nuclear systems, utilize liquid metals with low Prandtl numbers as coolants. The flow of liquid metal within the fuel assembly often exists in a mixed convection regime.

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow

Advanced Materials Interfaces, EarlyView.
A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

Advanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Convective Mixing Induced by Acid–Base Reactions

The Journal of Physical Chemistry B, 2011
When two miscible solutions, each containing a reactive species, are put in contact in the gravity field, local variations in the density due to the reaction can induce convective motion and mixing. We characterize here both experimentally and theoretically such buoyancy-driven instabilities induced by the neutralization of a strong acid by a strong ...

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.
