THE PHYSICAL NATURE OF LUMINESCENCE PULSATIONS IN FLUXES HEATED BY ARC DISCHARGES,

Abstract

A photographic study of the luminescence in an argon gas flow was carried out to clarify the nature and origin of the luminescence pulsations in gas flows heated by an electric dc arc discharge. Two types of arc discharge anodes were used and the dependence of the flow rate on the time, anode type, and discharge current was determined. Producing the results shown graphically. The frequency of luminescent pulsations was in the region of 15-30 khertz, and the experimentally determined flow rates were in fair agreement (20-25 percent) with theoretical results, calculated in terms of the argon flow rate and discharge power balance. The experimental results point to an acoustical nature of the luminescent pulsations observed in gaseous flows heated by arc discharges. (Author)
