[HTML][HTML] Microfluidics with fluid walls

EJ Walsh, A Feuerborn, JHR Wheeler, AN Tan… - Nature …, 2017 - nature.com
Microfluidics has great potential, but the complexity of fabricating and operating devices has
limited its use. Here we describe a method — Freestyle Fluidics — that overcomes many …

Heat transfer model for gas–liquid slug flows under constant flux

PA Walsh, EJ Walsh, YS Muzychka - International Journal of Heat and Mass …, 2010 - Elsevier
This paper investigates the mechanisms leading to enhanced heat and/or mass transfer rates
in two-phase non-boiling slug flows. The problem is analyzed in a minichannel geometry …

Microfluidic chambers using fluid walls for cell biology

…, AN Tan, H Walker, PA Walsh… - Proceedings of the …, 2018 - National Acad Sciences
Many proofs of concept have demonstrated the potential of microfluidics in cell biology.
However, the technology remains inaccessible to many biologists, as it often requires complex …

[HTML][HTML] Suicidal chemotaxis in bacteria

…, JHR Wheeler, C Deroy, SC Booth, EJ Walsh… - Nature …, 2022 - nature.com
Bacteria commonly live in surface-associated communities where steep gradients of
antibiotics and other chemical compounds can occur. While many bacterial species move on …

Raising fluid walls around living cells

…, C Deroy, AA Castrejón-Pita, PR Cook, EJ Walsh - Science …, 2019 - science.org
An effective transformation of the cell culture dishes that biologists use every day into microfluidic
devices would open many avenues for miniaturizing cell-based workflows. In this article…

Experimental investigation into the routes to bypass transition and the shear-sheltering phenomenon

D Hernon, EJ Walsh, DM McELIGOT - Journal of Fluid Mechanics, 2007 - cambridge.org
The objective of this investigation is to give experimental support to recent direct numerical
simulation (DNS) results which demonstrated that in bypass transition the flow first breaks …

Prandtl and capillary effects on heat transfer performance within laminar liquid–gas slug flows

JA Howard, PA Walsh, EJ Walsh - International Journal of Heat and Mass …, 2011 - Elsevier
This paper investigates a two-phase non-boiling slug flow regime for the purposes of enhancing
heat transfer in microchannel heat sinks or compact heat exchangers. The primary focus …

Jet‐Printing Microfluidic Devices on Demand

…, AA Castrejón‐Pita, PR Cook, EJ Walsh - Advanced …, 2020 - Wiley Online Library
There is an unmet demand for microfluidics in biomedicine. This paper describes contactless
fabrication of microfluidic circuits on standard Petri dishes using just a dispensing needle, …

[HTML][HTML] Predicting flows through microfluidic circuits with fluid walls

…, F Nebuloni, C Soitu, PR Cook, EJ Walsh - Microsystems & …, 2021 - nature.com
The aqueous phase in traditional microfluidics is usually confined by solid walls; flows through
such systems are often predicted accurately. As solid walls limit access, open systems are …

Effects of pressure gradients on entropy generation in the viscous layers of turbulent wall flows

DM McEligot, KP Nolan, EJ Walsh, E Laurien - International Journal of Heat …, 2008 - Elsevier
By employing results of direct numerical simulations, it is possible to examine entropy
generation due to friction in the viscous layers of turbulent flows with significant streamwise …
