Figure 15.
The panel a shows velocity contours at 0.25, 0.38, and 0.6 milli pascal seconds, with x from negative 300 to 300 micrometres and velocity from 0 to 60 metres per second. Graph b shows jet diameter decreasing from about 6.33 to about 6.12 micrometres, then rising to about 6.15 micrometres. Graph c shows jet length decreasing from about 126 to about 83 micrometres, then increasing to about 96 micrometres.Viscosity influence on the EFF jet diameter and length at a gas pressure of 2 kPa, a liquid flow rate of 0.75 ml/h and an electric potential of 0.75 kV
Note(s): The figure shows (a) the gas velocity field with streamlines inside the capillary needle, (b) jet diameter and (c) jet length with standard deviation in grey colour
