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 ...

A Model Intercomparison Study of Mixed‐Phase Clouds in a Laboratory Chamber

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Supercooled liquid water often persists in mixed‐phase clouds for hours to days, even though a simple, well‐mixed Wegener‐Bergeron‐Findeisen model predicts rapid depletion of liquid water in the presence of ice. The persistence is well documented, but the relative importance of the maintaining mechanisms remains uncertain.

Analysis of Turbulent Free Convection in a Rectangular Rayleigh-Benard Cell [PDF]

, 2007
The present study compares results of direct numerical simulations of thermal convection within a rectangular geometry with Rayleigh-Benard convection in thin fluid layers and cylindrical geometries.

Rayleigh-Bénard convection at high Rayleigh number and infinite Prandtl number: asymptotics and numerics

, 2013
The problem of fast viscous steady Rayleigh-Bénard convection in a rectangular enclosure is revisited using asymptotic and numerical methods. There are two generic cases: in the first, there is zero shear stress at all boundaries; in the second, there ...

The Coriolis Effects in Parameterization of Atmospheric Turbulence and Convection

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The Coriolis effect can deflect turbulent momentum flux and anisotropy of turbulent kinetic energy. This Coriolis turbulent deflection is usually omitted in parameterizations of atmospheric turbulence and convection. However, previous large‐eddy simulations (LES) found that the nontraditional Coriolis terms (NCTs) can enhance vertical velocity

Topographically Controlled Marangoni-Rayleigh-Bénard Convection in Liquid Metals

Fluids, 2021
Convection induced in a layer of liquid with a top free surface by a distribution of heating elements at the bottom can be seen as a variant of standard Marangoni–Rayleigh–Bénard Convection where in place of a flat boundary at constant temperature ...

High‐Resolution LiDAR Observations for Coupled Effects of Dry‐Air Entrainment and Haze‐Cloud Interactions on Cloud Vertical Structure

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study demonstrates the high‐resolution profiling of cloud microphysics in a laboratory chamber using Time‐Correlated Single Photon Counting (TCSPC) LiDAR. We present a novel retrieval method to derive vertical extinction (σ) $(\sigma )$ profiles, constrained by in situ measurements, to diagnose responses to dry‐air entrainment.

Fluid Convection, Constraint and Causation [PDF]

, 2011
Complexity–nonlinear dynamics for my purposes in this essay–is rich with metaphysical and epistemological implications but is only recently receiving sustained philosophical analysis.

Physics‐Informed Machine Learning Framework to Retroactively Estimate Mantle Thermal Convection From Partial Geophysical Observations

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Mantle convection drives the solid Earth, powering plate motions, volcanism, and earthquakes while regulating planetary heat loss. Reconstructing its history is hampered by sparse, noisy observations concentrated near the surface and the present day. Here I develop an inverse physics‐informed neural network framework to estimate mantle thermal

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
