This paper presents an experimental investigation of a charge injection electrostatic pressure swirl nozzle. The work forms part of the design and development of electrospray nozzle for practical oil burner application. The designed nozzle used in the experiment consists of a sharp pointed tungsten wire as a charge injector and the nozzle body grounded. The spray characteristics of the nozzle have been investigated by using a kerosine without active surface agent. The liquid breakup length decreased while the spray angle increased with an increase in applied voltage and injection pressure. An empirical equation to predict the breakup length for electrostatic pressure-swirl nozzle have been suggested. The experimental result was within the range of the predicted equation. An applied voltage of -10 kv result a decreased of the sauter mean diameter (SMD) at different radial distance.
