Settling of inertial particles in turbulent Rayleigh-Bénard convection [PDF]
Physical Review Fluids, 2020 The settling behaviour of small inertial particles in turbulent convection is a fundamental problem across several disciplines, from geophysics to metallurgy. In a geophysical context, the settling of dense crystals controls the mode of solidification of

Surface deflection in Rayleigh-Benard convection
Journal de Physique, 1989 The problem of the deformation of a free upper surface in a convective layer subjected to an adverse temperature gradient is analyzed. An analytical expression for the amplitude of the surface deflection in terms of the fluid layer parameters has been obtained when buoyancy force is the responsible mechanism for instability (thick layers).

Comparison of computational codes for direct numerical simulations of turbulent Rayleigh–Bénard convection [PDF]
, 2018 Computational codes for direct numerical simulations of Rayleigh–Benard (RB) convection are compared in terms of computational cost and quality of the solution. As a benchmark case, RB convection at Ra = 10 8 and Pr = 1 in a periodic domain, in cubic and

Sparse nonlinear models of chaotic electroconvection
Royal Society Open Science, 2021 Convection is a fundamental fluid transport phenomenon, where the large-scale motion of a fluid is driven, for example, by a thermal gradient or an electric potential. Modelling convection has given rise to the development of chaos theory and the reduced-

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.

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 ...

The effects of Ekman pumping on quasi-geostrophic Rayleigh–Bénard convection [PDF]
Journal of Fluid Mechanics, 2016 Numerical simulations of three-dimensional rapidly rotating Rayleigh–Bénard convection are performed by employing an asymptotic quasi-geostrophic model that incorporates the effects of no-slip boundaries through (i) parametrized Ekman pumping boundary ...

Study on the Instability of Two-Phase Flow in the Heat-Absorbing Tube of Trough Solar Collector
International Journal of Photoenergy, 2017 The Marangoni effect and Rayleigh-Benard effect in the two-phase region of solar trough heat-absorbing tube are simulated by FTM (front tracking method). Considering the Marangoni effect alone, although surface tension gradient and surface tension affect
