Accurate determination of stability characteristics of spatially modulated shear layers

S Panday, JM Floryan - Journal of Fluid Mechanics, 2023 - cambridge.org
We present a method for accurately determining the stability characteristics of spatially
modulated shear layers. The algorithm can handle arbitrary commensurate states, which are …

Propulsion due to thermal streaming

JM Floryan, S Panday, SA Aman - Journal of Fluid Mechanics, 2023 - cambridge.org
We demonstrate that the relative motion of horizontal parallel plates can be generated using
patterned heating. This movement is driven by nonlinear thermal streaming associated with …

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 …

Experiments on thermal drift

A Inasawa, K Hara, JM Floryan - Physics of Fluids, 2021 - pubs.aip.org
Thermal drift is a horizontal flow driven by a pattern interaction effect occurring on a solid
surface; that is, the flow is driven by an interaction between surface topography and the …

The role of vibrations for reducing the resistance in the relative movement of parallel plates

JM Floryan, NN Haq - Journal of Fluid Mechanics, 2022 - cambridge.org
The effect of surface vibrations on the propulsion augmentation and resistance in the relative
movement of parallel plates has been studied. The analysis was focused on monochromatic …

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 …

Numerical analysis of laminar-drag-reducing grooves

A Mohammadi, JM Floryan - Journal of Fluids …, 2015 - asmedigitalcollection.asme.org
The performance of grooves capable of reducing shear drag in laminar channel flow driven
by a pressure gradient has been analyzed numerically. Only grooves with shapes that are …

Use of heated corrugations for propulsion

JM Floryan, SA Aman, S Panday - Journal of Fluid Mechanics, 2024 - cambridge.org
We show that a heating pattern applied to a surface with a corrugation pattern generates a
propulsive effect. The same heating pattern applied to a smooth surface creates propulsion …

On the peristaltic pumping

JM Floryan, S Panday, KM Faisal - Physics of Fluids, 2021 - pubs.aip.org
Peristaltic pumping in a two-dimensional conduit using vibrations in the form of traveling
waves has been investigated. Two qualitatively different responses producing vastly …
