Figure 11.
The panel a shows velocity contours at 0.5, 0.75, and 1.5 millilitres per hour, with x from negative 300 to 300 micrometres and velocity from 0 to 60 metres per second. Graph b shows jet diameter increasing from about 3.4 micrometres at 0.5 millilitres per hour to 10 micrometres at 1.5 millilitres per hour. Graph c shows liquid flow rate from 0.25 to 1.50 millilitres per hour and jet length from 0 to 500 micrometres. Jet length increases from about 50 micrometres at 0.5 millilitres per hour to about 450 micrometres at 1.5 millilitres per hour.Liquid flow rate influence on the EFF jet diameter and length at a gas pressure of 2 kPa and the 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
