Therefore, this study focused on the experiment and analysis of stable region. The limitation of original design was that the flow rates through three filler holes were controlled by the same pump. In order to extend the range of stable region, the addition of another pump for controlling one injection flow rate could benefit the successful generation of double-emulsion droplet. Parameter measurements were performed for analyzing the effect of new independent flow rate through the filler hole on the sizes of oil droplet and water droplet, and then the size of droplet could be controlled via the adjustment of flow rates through the filler holes.
