Convective shutdown in a porous medium at high Rayleigh number
Convection in a closed domain driven by a dense buoyancy source along the upper boundary soon starts to wane owing to the increase of the average interior density.

Two-Dimensional Lattice Boltzmann for Reactive Rayleigh–Bénard and Bénard–Poiseuille Regimes
Entropy, 2015 We perform a computer simulation of the reaction-diffusion and convection that takes place in Rayleigh–Bénard and Bénard–Poiseuille regimes. The lattice Boltzmann equation (LBE) is used along with the Boussinesq approximation to solve the non-linear ...

Numerical Study of Rotating Thermal Convection on a Hemisphere
Fluids, 2020 Numerical simulations of rotating two-dimensional turbulent thermal convection on a hemisphere are presented in this paper. Previous experiments on a half soap bubble located on a heated plate have been used for studying thermal convection as well as the

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.This study examines approximate analytical solutions of the time‐fractional Swift–Hohenberg equation involving the Caputo–Fabrizio fractional derivative. The main objective of this study is to investigate efficient analytical approximation techniques using the Yang transform Adomian decomposition method (YTADM).

Self‐Organization of Redeposited Binder Nanoparticles in Cubic Boron Nitride Materials
Small, Volume 21, Issue 52, December 29, 2025.The article reveals a novel approach to forming micro‐spherical agglomerates through nanosecond laser irradiation, enabling rapid growth of titanium nanoparticles in air. It explores the self‐organisation of redeposited Ti nanoparticles on cubic boron nitride composites, detailing structural and chemical transformations that pave the way for innovative

Angewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

Extensive chaos in Rayleigh-Bénard convection [PDF]
, 2007 Using large-scale numerical calculations we explore spatiotemporal chaos in Rayleigh-Bénard convection for experimentally relevant conditions. We calculate the spectrum of Lyapunov exponents and the Lyapunov dimension describing the chaotic dynamics of ...

Nonlinear two-dimensional Rayleigh-Bénard convection [PDF]
, 2014 Two dimensional Rayleigh-Bénard convection in a Boussinesq fluid is the simplest possible system that exhibits convective instability. Moreover it contains the same basic physics as occurring in many geophysical and astrophysical systems, such as the ...
