Modulation of turbulent Rayleigh-Bénard convection under spatially harmonic heating

CB Zhao, YZ Zhang, BF Wang, JZ Wu, KL Chong… - Physical Review E, 2022 - APS
We numerically study turbulent Rayleigh-Bénard (RB) convection under spatial temperature
modulation, where the bottom temperature varies sinusoidally around a mean value in …

Wavenumber lock-in and spatial parametric resonance in convection

MZ Hossain, JM Floryan - Journal of Fluid Mechanics, 2022 - cambridge.org
Analysis of convection driven by spatial periodic heating shows a wealth of responses due
to Prandtl number dependence. The primary convection is delineated by the heating …

Natural convection and thermal drift

A Abtahi, JM Floryan - Journal of Fluid Mechanics, 2017 - cambridge.org
An analysis of natural convection in a horizontal, geometrically non-uniform slot exposed to
spatially non-uniform heating has been carried out. The upper plate is smooth and …

Instabilities of natural convection in a periodically heated layer

MZ Hossain, JM Floryan - Journal of Fluid Mechanics, 2013 - cambridge.org
Natural convection in an infinite horizontal layer subject to periodic heating along the lower
wall has been investigated using a combination of numerical and asymptotic techniques …

Some fundamental issues in buoyancy-driven flows with implications for geophysical and astrophysical systems

KQ Xia, KL Chong, GY Ding, L Zhang - Acta Mechanica Sinica, 2025 - Springer
Buoyancy-driven flows are prevalent in a wide range of geophysical and astrophysical
systems. In this review, we focus on three pivotal effects that significantly influence the …

Drag reduction in a thermally modulated channel

MZ Hossain, JM Floryan - Journal of Fluid Mechanics, 2016 - cambridge.org
Flow in a horizontal channel exposed to external heating which results in sinusoidal
temperature variations along the upper and lower walls with a phase shift between them has …

Natural convection in a horizontal fluid layer periodically heated from above and below

MZ Hossain, JM Floryan - Physical Review E, 2015 - APS
Natural convection in a horizontal slot heated from above and from below has been
considered. Each heating has a certain spatial distribution. It has been demonstrated that a …

Natural convection in a fluid layer periodically heated from above

MZ Hossain, JM Floryan - Physical Review E, 2014 - APS
Natural convection in a horizontal layer subject to periodic heating from above has been
studied. It is shown that the primary convection leads to the cooling of the bulk of the fluid …

Mixed convection in a periodically heated channel

MZ Hossain, JM Floryan - Journal of Fluid Mechanics, 2015 - cambridge.org
Mixed convection in a channel with flow driven by a pressure gradient and subject to
spatially periodic heating along one of the walls has been studied. The pattern of the heating …

Experiments on flows in channels with spatially distributed heating

A Inasawa, K Taneda, JM Floryan - Journal of Fluid Mechanics, 2019 - cambridge.org
Flows in channels exposed to spatially distributed heating were investigated. Such flows are
of interest as theoretical analyses suggest that heating leads to the reduction of pressure …
