Fig. 3: Experimental data and modelling.

A The Taylor cone area measured for different combinations of voltage and pressure under constant collection speed and temperature. B The jet angle measured for different combinations of voltage and pressure under constant collection speed and temperature. C A polynomial function relating Taylor cone area to fibre diameter ratio decreases with increasing collection speed. Graphical representation of the trained neural network model of (D) jet angle (E) the Taylor cone area, and (F) fibre diameter at the collection speed of 800 mm/min and temperature of 75 °C.
