Figure 3
Co-flow thickness in the T-junction with PSII buffer in mode 1 at different flow rates and contact angles. Co-flow thickness was estimated for contact angles of 143, 71 and 54°. The co-flow thickness decreases with decreasing contact angle. For a flow-rate ratio of 3, instead of co-flow, droplet generation was observed for a hydrophobic condition (contact angle of 143°). The error bars indicate the standard deviation of the co-flow thickness. |
