Skin-Friction and Forced Convection from Rough and Smooth Plates

open access: yes, 2020
The current models for skin-friction drag from a plate with a rough surface are derived by analogy to flow within pipes having rough interiors. But this analogy fails at low Reynolds number (Re) flow rates because the boundary-layer must compress into ...

P3HT‐Based Electroactive Films for In Vitro Neuronal Cell Interfacing

open access: yesAdvanced Materials Interfaces, EarlyView.
Reducing the mechanical mismatch between bioelectronic devices and tissue is crucial for enhancing the characteristics of biointerfaces that better mimic the biological tissues. This work investigates the physico‐chemical properties of tunable nanostructured surfaces obtained from a blend of P3HT and MWCNT electroactive polymer.

Heat flux scaling in turbulent Rayleigh-B\'enard convection with an imposed longitudinal wind

open access: yes, 2013
We present a numerical study of Rayleigh-B\'enard convection disturbed by a longitudinal wind. Our results show that under the action of the wind, the vertical heat flux through the cell initially decreases, due to the mechanism of plumes-sweeping, and ...

Investigating the Mechanism of Ion Concentration Polarization Within Nanofluidic Hydrogel Membranes: Experiment and Simulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Molecular dynamics simulations are employed to model ion concentration polarization (ICP) at the nanoscale, revealing fundamental electrokinetic behaviors that align with experimental observations. The study demonstrates how membrane charge, ionic strength, and electric fields affect ion localization and biomolecule trapping, providing mechanistic ...

Engineering correlations of variable-property effects on laminar forced convection mass transfer for dilute vapor species and small particles in air [PDF]

open access: yes
A simple engineering correlation scheme is developed to predict the variable property effects on dilute species laminar forced convection mass transfer applicable to all vapor molecules or Brownian diffusing small particle, covering the surface to ...

Durable Low‐Interfacial Toughness PDMS/SiO2 Coatings with Superior Anti‐Icing and Large‐Scale Deicing Performance in the Natural Field

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐interfacial toughness PDMS/SiO2 coatings are applied to aluminum substrates and tested under natural high‐altitude conditions. The coatings demonstrate strong anti‐icing, icephobic, and large‐scale deicing performance. Field results highlight delayed freezing, reduced ice adhesion, and stable durability, offering practical insights into the use of ...
