Figure 9.
The panel a shows velocity contours at 0.25, 0.5, 0.75, and 1 kilovolts, with x from negative 200 to 500 micrometres and velocity from 0 to 60 metres per second. Graph b shows jet diameter decreasing from about 10.3 micrometres at 0.25 kilovolts to about 4.9 micrometres at 1 kilovolt. Graph c shows jet length increasing from about 85 micrometres at 0.25 kilovolts to about 340 micrometres at 0.5 kilovolts, decreasing to about 90 micrometres at 0.75 kilovolts, then increasing to about 110 micrometres at 1 kilovolt and about 190 micrometres at 1.25 kilovolts.Electric potential influence on the EFF
Note(s): The figure shows (a) the velocity and volume fraction fields, (b) jet diameter and (c) jet length with standard deviation in grey colour. Gas pressure was 2 kPa, and the liquid flow rate was 0.75 ml/h for all cases
