内容記述(抄録等)Dynamic behavior of the three phase rotating arc which was ignited between three radial electrodes in the nozzle cross section and the plasma jet was studied by the high speed photography. Using the taper type nozzle (AN52-nozzle) having the taper in the constrictor entrance region and the no-taper type nozzle (AN50-nozzle), experiments were made at the arc current 20∿73A, the total gas flow rate 10∿20l/min and the three kinds of gas flow pattern which were the cross flow pattern, vortex flow pattern and mixed flow pattern mixed the cross flow with vortex flow. The arc igniting condition and its rotating aspect were different in the nozzle configuration and the gas flow pattern. In the cross gas flow pattern, when the arc current was small, the arc was straightly maintained between the electrodes, but increasing the arc current, it was bended toward the nozzle center axis. On the other hand, in the vortex and the mixed flow pattern, the arc was became hair-pin configuration near the electrode situated the downstream and it was always maintained near the nozzle center axis irrespective of the arc operating parameter (arc current, gas flow rate). The distance (r) between the arc and the nozzle center axis in the nozzle cross section was 1.05∿1.75mm for the cross flow pattern but r of AN52-nozzle and AN50-nozzle was 0.4∿1.2mm, 0.6∿1.6mm respectively for the mixed gas flow pattern. The plasma jet, which was generated by providing the mixed gas flow pattern of which mixed ratio Q (cross gas flow rate)/Q (cross gas flow rate + vortex gas flow rate) was 0.5 to AN52-nozzle, had so small fluctuation range in the radial and the axial direction that it was stable and its length was longest.
