On the role of surface grooves in the reduction of pressure losses in heated channels

MZ Hossain, JM Floryan - Physics of Fluids, 2020 - pubs.aip.org
Pressure-gradient-driven flows in grooved horizontal channels were investigated. The
results show that a significant reduction in pressure losses can be achieved by exposing …

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 …

Heating-induced drag reduction in relative movement of parallel plates

JM Floryan, S Shadman, MZ Hossain - Physical Review Fluids, 2018 - APS
An external force is required to maintain the relative movement of horizontal plates. It is
shown that this force is reduced when the plates are subject to a spatially distributed …

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 …

Transition of natural convection on a cooled circular surface with heated annular extension

M Qiao, Z Gao, S Li, H Zhang, F Xu - International Communications in Heat …, 2024 - Elsevier
Transition of natural convection on a circular cooled surface with heated annular extension
is investigated in the present study by numerical simulation. Flow features and regimes of …

On the formation of thermal drift

A Abtahi, JM Floryan - Physics of Fluids, 2018 - pubs.aip.org
It has been recently shown [A. Abtahi and JM Floryan,“Natural convection and thermal drift,”
J. Fluid Mech. 826, 553 (2017)] that a horizontal flow, the thermal drift, can be created by …

Use of heated grooves for reduction in friction resistance

JM Floryan, S Panday, SA Aman - Physics of Fluids, 2024 - pubs.aip.org
An analysis of the use of heated grooves for resistance reduction was carried out. The model
problem consisted of two parallel plates in a relative motion. The stationary plate was …

Convective heat transfer in non-uniformly heated corrugated slots

A Abtahi, JM Floryan - Physics of Fluids, 2017 - pubs.aip.org
An analysis of heat transfer in non-uniformly heated corrugated slots has been carried out. A
sinusoidal corrugation is placed at the lower plate that is exposed to heating consisting of …

Creation of streaks using heating patterns

S Panday, JM Floryan - Physics of Fluids, 2021 - pubs.aip.org
Streaks and rolls are of interest in mixing intensification. It is shown that they can be created
in a controlled manner in fully developed shear layers using spatially distributed heating …

Thermal drift in an inclined viscous fluid flow

MM Jovanović, SM Milanović, AZ Boričić… - Thermal …, 2023 - doiserbia.nb.rs
This paper considers viscous fluid flow in a slot between two parallel plates which start
inclining with respect to the horizontal line. The lower plate was heated and had non …
