Incompressible flows and the Boussinesq approximation: 50 years of CFD

open access: yesComptes Rendus. Mécanique, 2022
We offer a synthetic exposition on the state of the art for Computational Fluid Dynamics (CFD) relevant to the Navier–Stokes equations with the Boussinesq approximation, smoothly blending a history of the field with an accessible exposition of the ...

Sparse nonlinear models of chaotic electroconvection

open access: yesRoyal 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-

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

open access: yesJournal 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.

The Coriolis Effects in Parameterization of Atmospheric Turbulence and Convection

open access: yesJournal 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

The Rayleigh-Benard Convection in Rarefied Gases [PDF]

open access: yes, 1998
In the present paper we investigate the Rayleigh-Benard convection in rarefied gases and demonstrate by numerical experiments the transition from purely thermal conduction to a natural convective flow for a large range of Knudsen numbers from 0.02 downto

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

open access: yesGeophysical 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.

Oscillatory Instabilities of Two-Layer Rayleigh-Marangoni-Benard Convection [PDF]

open access: yes, 2006
The Rayleigh–Marangoni–Bénard convective instability (R–M–B instability) in the two-layer systems such as Silicone oil (10cSt)/Fluorinert (FC70) and Silicone oil (2cSt)/water liquids are studied.

Study on the Instability of Two-Phase Flow in the Heat-Absorbing Tube of Trough Solar Collector

open access: yesInternational 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
