Quality by Design Approach to Advanced Particle Engineering, Process Optimisation and Upscaling of Electrohydrodynamic Atomisation Technology
… 8-nozzle system with capabilities of large scale electrospraying of drug particles. Studies on the droplet dynamics showed the impact of the electric field from each nozzle on the spray pattern altering the spray projection of INDO in ethanol (EtOH). The voltage utility graph also demonstrated a …

Formation of polymer nanofibers from electrified fluid jets
… the jet disintegrates into fine droplets, i.e., electrospraying. For sufficiently large jet radii, experiments have verified the theoretical prediction that the dispersal of fluid results from the growth of a non-axisymmetric conducting mode along the jet, which subsequently breaks into droplets …
