Diffusion‐Free Scaling in Rotating Spherical Rayleigh‐Bénard Convection [PDF]

open access: yesGeophysical Research Letters, 2021
Direct numerical simulations are employed to reveal three distinctly different flow regions in rotating spherical Rayleigh‐Bénard convection. In the high‐latitude region I vertical (parallel to the axis of rotation) convective columns are generated ...

Turbulent superstructures in Rayleigh-Bénard convection [PDF]

open access: yesNature Communications, 2018
Turbulent fluids in nature, counter-intuitively, can exhibit large-scale order that persists for long times. Pandey et al. numerically characterize the formation of these superstructures in turbulent convection by separating the fast motions at small ...

Transient Localized Rotating Structures in a Suspension of Highly Thermophilic Nanoparticles

open access: yesFrontiers in Physics, 2022
A thermophilic suspension of nanoparticles heated from below exhibits a complex stability diagram determined by the competition between the stabilizing flux of nanoparticles induced by thermophoresis and the destabilizing flux determined by thermal ...

Natural convection in a model chamber with the Boussinesq approximation utilization [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2017
The paper presents numerical analysis of heat transfer inside a model chamber in time after entering an object of elevated temperature therein. As a result of the temperature difference between the object and the environment in the room, natural ...

Note on the Early Thermoelastic Stage Preceding Rayleigh–Bénard Convection in Soft Materials

open access: yesFluids, 2022
In this paper, we focus on the first stage of transition to Rayleigh–Bénard convection in soft-jammed systems (yield stress fluids) confined in a parallelepiped box heated from the bottom.

Numerical simulation of Rayleigh–Bénard convection with supercritical carbon dioxide in a shallow cavity

open access: yesFrontiers in Energy Research, 2023
A numerical simulation of Rayleigh–Bénard convection with supercritical carbon dioxide is presented in this paper. A shallow cavity with an aspect ratio of 4 is selected as a container that is fully filled with supercritical carbon dioxide.

Rayleigh-Bénard convection with magnetic field [PDF]

open access: yesTheoretical and Applied Mechanics, 2003
We discuss the solution of the small perturbation equations for a horizontal fluid layer heated from below with an applied magnetic field either in vertical or in horizontal direction. The magnetic field stabilizes, due to the Lorentz force, more or less

Marginal Stability of Oscillatory Bénard-Marangoni Convection With Internal Heat Generation

open access: yesJournal of Computing Research and Innovation, 2023
The onset of oscillatory Benard-Marangoni convection in a horizontal fluid layer with internal heat generation and a deformable free surface is studied using an analytical technique employing the classical linear stability theory.

Numerical Analysis of Linear Traveling Wave in Rotating Rayleigh–Bénard Convection with an Adiabatic Sidewall

open access: yesFluids, 2023
In rotating Rayleigh–Bénard problems, convection with traveling waves may occur near the sidewalls. The Rayleigh number, Taylor number and Prandtl number are involved in this phenomenon, and the convection mode is determined depending on their values. We
