Turbulent superstructures in Rayleigh-Bénard convection [PDF]
Nature 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 ...

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

Thermodynamic Analysis of Bistability in Rayleigh–Bénard Convection [PDF]
Entropy, 2020 Bistability is often encountered in association with dissipative systems far from equilibrium, such as biological, physical, and chemical phenomena.

Rayleigh-Bénard convection with magnetic field [PDF]
Theoretical 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

Transient Localized Rotating Structures in a Suspension of Highly Thermophilic Nanoparticles
Frontiers 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]
Biuletyn 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 ...

Unsteady Flow and Mass Transfer Induced by Rayleigh-Bénard-Marangoni Convection. [PDF]
, 2023 Acknowledgements: The simulations were performed on the supercomputer bwUniCluster 2.0 supported by the state of Baden-Württemberg, Germany through bwHPC.Evaporative cooling at the water surface is usually modelled by imposing a constant heat flux at the

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

Time-Periodic Cooling of Rayleigh–Bénard Convection
Fluids, 2021 The problem of Rayleigh–Bénard’s natural convection subjected to a temporally periodic cooling condition is solved numerically by the Lattice Boltzmann method with multiple relaxation time (LBM-MRT).
