Vertical heat transport at infinite Prandtl number for micropolar fluid

Archives of Mechanics, 2020
We investigate the upper bound on the vertical heat transport in the fully 3D Rayleigh–Bénard convection problem at the infinite Prandtl number for a micropolar fluid.

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.

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 ...

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 ...

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

Energy Spectra in Rayleigh-Benard Convection

Journal of Physics: Conference Series, 2011
We present a numerical study of the energy spectra and fluxes in the inertial range of turbulent Rayleigh-Benard convection for a wide range of Prandtl number. We consider both free-slip and no-slip conditions for our simulation. Our results support the Kolmogorov-Obukhov (KO) scaling for velocity field for zero-Prandtl number and low-Prandtl number (P

Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Evaluating the Collision‐Coalescence Process in Idealized Cloud Convection Using Large‐Eddy Simulations With Lagrangian Microphysics

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Drizzle initiation through the collision and coalescence of cloud droplets plays a crucial role in warm cloud precipitation. Recent theoretical studies suggest that the influence of collisional growth on the droplet size distribution can be quantified by a non‐dimensional drizzle number (Dz).

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.
