Droplet Device
To answer the questions mentioned at the introduction, a droplet device with a single oil inlet and a single water inlet is used (see Figure 1). Both channels will end in a so called flow-focusing cross junction, where the droplets will be formed. The fluids will first pass a filter to minimize blockage at the cross junction nozzle. The curved channels just before the cross junction are fluid resistors and will create a laminar flow. It is possible to control the droplet size and droplet formation speed, by alternating both the oil flow as the water flow.
