A Model of Rayleigh-Bénard Convection

, 2013
This chapter presents a model of Rayleigh–Bénard convection. It first describes the fundamental dynamics expected in a fluid that is convectively stable and in one that is convectively unstable, focusing on thermal convection and internal gravity waves ...

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

ROTATING RAYLEIGH-BENARD CONVECTION

TASK Quarterly, 2008
In the this paper our results on the natural convection in an enclosed rotating cavity are presented. We have focused our attention on the influence of the Rayleigh and Taylor numbers on the flow structure.

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.

Rayleigh-Bénard Convection for Nanofluids for More Realistic Boundary Conditions (Rigid-Free and Rigid-Rigid) Using Darcy Model [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2019
In this article, Rayleigh-Bénard convection for nanofluids for more realistic boundary conditions (rigid-free and rigid-rigid) under the influence of the magnetic field is investigated.

Multiple Steady States in Laminar Rayleigh–Bénard Convection of Air

Fluids, 2023
In this article, we report on numerical simulations of laminar Rayleigh–Bénard convection of air in cuboids. We provide numerical evidence of the existence of multiple steady states when the aspect ratio of the cuboid is sufficiently large.

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).

Rayleigh-Bénard-Taylor Convection of Newtonian Nanoliquid

, 2017
In the paper we make linear and non-linear stability analyses of Rayleigh-Bénard convection of a Newtonian nanoliquid in a rotating medium (called as Rayleigh-Bénard-Taylor convection).

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.
