Convection in fluid and porous media [PDF]

open access: yes, 2003
The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

Initial layer problem of the Boussinesq system for Rayleigh-Bénard convection with infinite Prandtl number limit

open access: yesOpen Mathematics, 2018
The main purpose of this paper is to study the initial layer problem and the infinite Prandtl number limit of Rayleigh-Bénard convection with an ill prepared initial data.

Controlling the Collective Transport of Large Passive Particles With Suspensions of Microorganisms

open access: yesSmall, Volume 22, Issue 18, 25 March 2026.
Directional light stimuli induce the accumulation of microalgae in suspensions of Chlamydomonas reinhardtii. This accumulation triggers large scale bioconvection rolls capable of macroscale transport. Exploiting these bioconvective flows enables to collectively transport of hundreds of large passive particles, paving the way for future applications in ...

Moist Rayleigh-Benard convection

open access: yes, 2015
We report the observations from turbulent thermal Rayleigh-Benard convection experiment with a two-phase liquid-vapor binary mixture. Evaporation/condensation processes in a turbulent convection are accompanied by the formation of cloud like structures ...

Impacts of high viscosity variation and internal heating on mantle convection in different aspect ratio cells

open access: yesHeliyon
This study examines the Rayleigh-Bénard convection model with free slip boundary conditions appropriate for the Earth's mantle in narrow and elongated cells with aspect ratios of 1:2 and 2:1, respectively.

Slantwise Convection and Heat Transport in Icy Moon Oceans

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.

Two-Dimensional Lattice Boltzmann for Reactive Rayleigh–Bénard and Bénard–Poiseuille Regimes

open access: yesEntropy, 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

open access: yesFluids, 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

Large Aerosol Particles Favor Haze Conditions Through Limitations on Water Budget and Activation Kinetics

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Experiments in the Pi Convection‐Cloud Chamber conducted by systematically changing the diameter of injected dry aerosol particles while holding the temperature difference constant demonstrate that dry diameter strongly influences the onset of haze‐dominated conditions.
