Entropy Generation Analysis of Unsteady Magnetohydrodynamic Buoyancy‐Driven Nanofluid Flow in a Porous Vertical Channel With Thermal Radiation and Chemical Reaction

Energy Science &Engineering, EarlyView.
An unsteady, laminar, incompressible flow of an electrically conducting viscous nanofluid between two infinite vertical porous plates separated by a distance b $b$ is considered. The flow is driven by buoyancy forces arising from temperature and concentration differences.

Impact of Hartmann number and aspect ratio on the heat and mass transfer characteristics in a hexagonal enclosure with a heated circular obstacle inside

Ain Shams Engineering Journal
Hyrdo-thermal performance study in enclosures or cavities is a very promising field of study for industrial components design and implementation. Previous studies have investigated various shapes and conditions, but there is a significant research gap in

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Climate Indices and Atmospheric Circulation Patterns Linked to East Asian Summer Wet‐Bulb Temperatures

International Journal of Climatology, EarlyView.
Summer wet‐bulb temperatures (Tw) have been rising across East Asia in recent decades, reflecting the intensification of humid heat. To isolate internally driven variability from the long‐term warming trend, EOF analysis was performed on linearly detrended Tw, revealing two dominant modes of spatially contrasting variability: a north–south dipole ...

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

An idealised model of convective hydration of the tropical tropopause layer. Part I: Model formulation and diagnostic approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We formulate an idealised model of convective overshoots that hydrate the tropical tropopause layer. We consider large‐eddy simulations of a turbulent buoyant plume that penetrates into a stably stratified layer carrying temperature‐dependent tracers that represent water vapour and ice.

Numerical Analysis of Double Diffusive Laminar Natural Convection in a Right Angle Triangular Solar Collector

Al-Khawarizmi Engineering Journal, 2013
A numerical study of the double-diffusive laminar natural convection in a right triangular solar collector has been investigated in present work. The base (absorber) and glass cover of the collector are isothermal and isoconcentration surfaces, while the

RETRACE Project: How to Enhance Resilience to Climate Risks in Pacific and Arctic Indigenous Communities?

Sustainable Development, EarlyView.
ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...
