Co-flow droplet generator for a two components chemical reaction (orange and white solutions are miscible). The axis of the bleu channel is not respect for preventing the flow rate variation around the droplets.

Flow rate variation inside a microfluidic channel. The droplet (orange) doesn’t felt all the flow rate field (in yellow). Du to that, this droplet has a different rate than the external liquid average speed.
