HIGH-TEMPERATURE ARC IN DENSE GAS
ABSTRAKT
The investigations of the powerful electric discharge in high density hydrogen were continued in IPE RAS. In these experiments the influence of discharge current magnitude, current rise rate and initial particle density on arc temperature was investigated. These experiments were performed under the following conditions: charge voltage of the capacitive energy supply 8.0−14.0 kV, stored energy 140−450 kJ, discharge current 200−600 kA, current rise rate 109−1010 A/s. The maximum particle density nmax, achieved just before the discharge was about 2.0×1022 cm−3. Arc temperature was calculated on the basis of measured electric parameters of arc and bright temperature of its outer layer.
It was revealed that increasing in initial particle density, discharge current magnitude and current rise rate leads to the reducing of arc diameter that results in increasing of temperature of the discharge channel. Obtained experimental data permits to define the main parameters of the discharge: temperature of arc channel, plasma conductivity and density of charged particles in the arc channel. It was estimated that temperature of arc central zone is achieved 3×105 K at the specified initial conditions.
