Description

This SIG aims at establishing a network around the topic of Drop Dynamics. The objective is to bring together experimentalists, theoreticians and numerical-modellers working on, but not limited to: pinch-off, drop formation/generation, coalescence, drop interactions, drop impact, spreading, splashing and applications (inkjet, sprays, microfluidics, drug delivery, etc.).

Overview

This Special Interest Group aims to encourage discussions and establish collaborative networks around the topic of Drop Dynamics. The objective is to bring together experimentalists, theoreticians and numerical modellers to study the topics (but not limited to!) of pinch-off, drop formation and generation, coalescence, drop interactions, drop impact, spreading and splashing, and applications of drops (inkjet, sprays, microfluidics, coatings, 3D printing). The membership to this group is open to the public and aimed to researchers and students working in the field of droplets. Please, email us to include your email to the circulation list.

Our membership offers an unmatched set of skills and expertise, ranging from fundamental asymptotic and high resolution numerical models (such as DNS, Lattice Boltzmann and Molecular Simulations), through state-of-the-art experimental techniques (such as ultra-high-speed image visualisation and holography), to applied research (microfluidics, inkjet, spray/combustion, and biofluids).

Below is a video presentation of the group's research areas.

Activities

 Special Interest Group meetings will be held twice a year.  Each meeting will cover  a combination of fundamental and applied research to encourage, foster, establish and strengthen collaboration between the groups.  Group leaders will be encouraged to bring research associates, assistants and graduate students to the meetings.
