Performance tuning of microfluidic flow-focusing droplet …
WebJan 4, 2024 · We present a web-based tool, DAFD, that predicts the performance and enables design automation of flow-focusing droplet generators. WebJul 25, 2012 · Flow-focusing devices consist of three inlet channels converging into a main channel via a narrow orifice as first mentioned by Anna et al. [14] and Dreyfus et al. [15]. The continuous phase flowing from two opposing side channels squeezes the dispersed phase flow while both phase flows go through the small orifice. Therefore, the stream of … greeley school peoria il
Ferrofluid droplet formation and breakup dynamics in a …
WebThis work aims at studying the expanding and breakup dynamics of the thread of a controllable dispersed phase under different flow rates in a microfluidic flow-focusing device. The whole formation process of ferrofluid droplets under no magnetic field (NM), a radial magnetic field (RM) and an axial magnetic field (AM) were investigated and ... WebFeb 6, 2024 · Abstract.
