IRREGULARS OF THE ELENBAAS-HELLER EQUATION SOLUTIONS FOR ELECTRIC ARC CANAL
Keywords:
electric arc, equation-tion Elenbaas-Geller, thermal conductivity, copper and air plasma, transport coefficients of energyAbstract
The numerical simulation shows the presence of irregular solutions of the Elenbass Heller equation in determining the radial structure of the electric arc canal. It is caused by the thermal conductivity nonmonotonic character. The calculations are performed on the example of copper-air plasma, where this conductivity has strongly pronounced maximums. The methodology and results of the determination of the transport coefficients in copper-air plasma with various ratios of the components are presented briefly. The results of calculations allow estimating the role of energy transport processes in the formation of the canal radial structure as well as the formation of the electric field strength dependence on the discharge current magnitude.
