Figure 3. Phase diagram showing flow behaviors influenced by channel dimension.

Figure 3

Inline graphic represents cone-shape tip, while the region of Inline graphic indicates the spindle-shape tip. Inline graphic marks the transition of droplet breakup location from focusing orifice to injection nozzle. Different symbol colors represent different cases (Table 1). Different symbol shapes distinguish flow behaviors, where square denotes cone-shape tip, circle is for spindle-shape tip, and triangle means breakup at injection nozzle. The phase diagram is obtained with Inline graphic and Inline graphic. Insets: snapshots of cone-shape tip, spindle-shape tip and breakup at focusing orifice and injection nozzle, respectively.
