Natural convection driven by the non-horizontal isothermal contours in an aqueous sessile droplet

Results in Engineering
Natural convection dominates heat and mass transfer in microscale droplet evaporation. Classical Rayleigh–Bénard theory states that convection occurs only above a critical Rayleigh number, yet persistent convection exists in evaporating sessile droplets ...

Topographically Controlled Marangoni-Rayleigh-Bénard Convection in Liquid Metals

Fluids, 2021
Convection induced in a layer of liquid with a top free surface by a distribution of heating elements at the bottom can be seen as a variant of standard Marangoni–Rayleigh–Bénard Convection where in place of a flat boundary at constant temperature ...

On the Cell Broadening of Mesoscale Cellular Convection in a Well‐Mixed Boundary Layer

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Understanding what controls the horizontal scale of mesoscale cellular convection is central to explaining cloud self‐organization and its radiative impacts. Using a hierarchy of large‐eddy simulations, we investigate cell broadening in a well‐mixed boundary layer by isolating the roles of radiation, cloud microphysics, and water vapor.

Instability of Two-Layer Rayleigh-Benard Convection with Interfacial Thermocapillary Effect

, 2004
The linear instability analysis of the Rayleigh-Allarangoni-Benard convection in a two-layer system of silicon oil 10cS and fluorinert FC70 liquids are performed in a larger range of two-layer depth ratios H, from 0.2 to 5.0 for different total depth H ...

Thermal Analysis of Phase Change Material Based Energy Storage Module With Triply Periodic Minimal Surfaces

Energy Storage, Volume 8, Issue 4, June 2026.
ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.

Localized Convection in Sputnik Planitia, Pluto

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The cellular plains on Sputnik Planitia (SP) are thought to originate from convection in the nitrogen ice layer that fills the basin. Whereas the cells toward the center of SP's cellular plains are wider and interconnected—features explained by vigorous convection—the cells near the margins are smaller and less contiguous, with some appearing ...

Morphological Regimes of Rotating Moist Convection

The Astrophysical Journal
Moist convection is a physical process in planetary atmospheres where the latent heat released by condensation acts as a buoyancy source that can enhance or even trigger an overturning convective instability.

Tailoring Defective Tungsten Oxide Aerogel Evaporator for Enhanced Solar Steam Generation and Heavy Metal Adsorption Toward Agricultural Irrigation

Carbon Neutralization, Volume 5, Issue 3, May 2026.
A cost‐effective defective WO3−x@cellulose aerogel composites that simultaneously convert wastewater into agricultural irrigation water through solar‐driven freshwater generation and heavy metal remediation was proposed. And the precision defect engineering of oxygen‐vacancy modulated WO3−x nanocrystals demonstrate excellent solar absorption efficiency
