Flow focusing method

WebThe T junction and the flow-focusing techniques are the main methods used to produce droplets (Figure 1). Both techniques require an accurate flow control system to achieve the desired droplet parameters – size and frequency. The T junction system injects the two phases orthogonally, forming the droplet at the channels’ intersection. WebApr 26, 2013 · This constitutes a fundamental change in the flow focusing method because it alters completely the dynamics and, therefore, the stability of the liquid source. Specifically, the absence of recirculation patterns for low and moderate-viscosity liquids enhances the flow stability, and prevents the liquid from dripping as the injected flow …
