Experiments on Droplet Collisions, Bounce, Coalescence and Disruption

-There has been a significant effort to understand the events that occur when two or more droplets collide. The majority of the early work, which dates from the 1960s, focused on droplet growth relating to precipitation and was thus limited to water droplet collision phenomena. Recently, studies have sought information on the collision behavior of fuel droplets for application to combustion spr...

A microfluidic method to study demulsification kinetics.

We present the results of experiments studying droplet coalescence in a dense layer of emulsion droplets using microfluidic circuits. The microfluidic structure allows direct observation of collisions and coalescence events between oil droplets dispersed in water. The coalescence rate of a flowing hexadecane-in-water emulsion was measured as a function of the droplet velocity and droplet concen...

Investigation of droplet coalescence in nanoparticle suspensions by a microfluidic collision experiment.

Understanding the phenomenon of droplet coalescence in nanoparticle suspensions is extremely important for the preparation of Pickering emulsions. A microfluidic platform, which can provide compulsive droplet collisions, was developed to imitate the droplet coalescence process in the early stages of emulsification. Microscope videos showed the variations in the droplet coalescence percentage, d...

Rebounding droplet-droplet collisions on superhydrophobic surfaces: from the phenomenon to droplet logic.

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. Furthermore, bouncing or coalescence can be easily controlled by process parameters. Thus by the controlled coalescence of r...
