Transitions between turbulent states in rotating Rayleigh-Bénard convection [PDF]

, 2009
Weakly rotating turbulent Rayleigh-Bénard convection was studied experimentally and numerically. With increasing rotation and large enough Rayleigh number a supercritical bifurcation from a turbulent state with nearly rotation-independent heat transport ...

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.

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

Small, 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 ...

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.

Slantwise Convection and Heat Transport in Icy Moon Oceans

Geophysical 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.

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).

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

Geophysical 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.

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.

GENETIC SOURCES AND TECTONOPHYSICAL REGULARITIES OF DIVISIBILITY OF THE LITHOSPHERE INTO BLOCKS OF VARIOUS RANKS AT DIFFERENT STAGES OF ITS FORMATION: TECTONOPHYSICAL ANALYSIS

Геодинамика и тектонофизика, 2015
The paper presents the first tectonophysical reconstruction of initial divisibility of the protolithosphere as a result of convection in the cooling primitive mantle. Initial division of the protolithosphere into separate masses, i.e.
