Abstract

This paper reports an observational analysis on droplet formation from a capillary-jet driven by centrifugal-gravity in a CDSD (Centrifuge-based droplet shooting device), and controlled synthesis of microbeads by instantaneous solidification of a sodium alginate solution jet breaking into drops owing to hydrodynamic instability. Our analysis may deepen understanding of micro capillary-jet and enable flexible fabrication of fluidic-based polymeric microbeads.
