Energy analysis of droplet jumping induced by multi-droplet coalescence: The influences of droplet number and droplet location

International Journal of Heat and Mass Transfer, 2018
Abstract Self-propelled droplet jumping phenomenon during condensation on superhydrophobic surfaces has various engineering applications such as heat transfer enhancement, hotspot cooling and anti-icing/frosting. Since most of the droplet jumping phenomena are induced by multi-droplet rather than two-droplet coalescence, understanding the influences ...

Swimming Droplets

Annual Review of Condensed Matter Physics, 2016
Swimming droplets are artificial microswimmers based on liquid droplets that show self-propelled motion when immersed in a second liquid. These systems are of tremendous interest as experimental models for the study of collective dynamics far from thermal equilibrium.

Droplet microfluidics

Lab on a Chip, 2008
Droplet-based microfluidic systems have been shown to be compatible with many chemical and biological reagents and capable of performing a variety of "digital fluidic" operations that can be rendered programmable and reconfigurable. This platform has dimensional scaling benefits that have enabled controlled and rapid mixing of fluids in the droplet ...

On a tweezer for droplets

Advances in Colloid and Interface Science, 2010
We describe the physics behind a peculiar feeding mechanism of a certain class of shorebirds, in which they transport their prey in droplets from their beak tips mouthwards. The subtle interplay between the drop and the beak's tweezering motion allows the birds to defy gravity through driving the drop upwards. This mechanism provides a novel example of

Atomic Force Microscopy of Emulsion Droplets:  Probing Droplet−Droplet Interactions

Langmuir, 2003
A method has been developed for attaching oil (tetradecane) droplets to the end of an atomic force microscopy (AFM) cantilever and for immobilizing droplets on a glass substrate. This approach has permitted the monitoring of droplet-droplet interactions in aqueous solution as a function of interdroplet separation.

Rebounding Droplet‐Droplet Collisions on Superhydrophobic Surfaces: from the Phenomenon to Droplet Logic

Advanced Materials, 2012
When water droplets impact each other while traveling on a superhydrophobic surface, we demonstrate that they are able to rebound like billiard balls. We present elementary Boolean logic operations and a flip-flop memory based on these rebounding water droplet collisions.

Numerical Investigation of Droplet-Droplet Coalescence and Droplet-Interface Coalescence

Volume 1A, Symposia: Advances in Fluids Engineering Education; Turbomachinery Flow Predictions and Optimization; Applications in CFD; Bio-Inspired Fluid Mechanics; Droplet-Surface Interactions; CFD Verification and Validation; Development and Applications of Immersed Boundary Methods; DNS, LES, and Hybrid RANS/LES Methods, 2014
The oil produced from offshore reservoirs normally contains considerable amount of water. The separation of water from oil is very crucial in petroleum industry. Studying the coalescence of two droplets or one droplet and interface can lead to better understanding of oil-water separation process.
