Abstract

Three dimensional non-stationary model of inductively coupled plasma torch for optical emission spectrometry was developed and experimentally tested. The processes of ignition and steady burning were considered. The effects of plasmoids formation and pulsations and rotation of the plasma jet were identified, experimentally confirmed and interpreted. Simulated results are in a good agreement with the experimental data obtained by Schlieren measurements.
