Thermal interruption performance of ultrahigh-pressure free-burning nitrogen arc
Abid, Fahim; Niayesh, Kaveh; Thimmappa, Shashidhara Basavapura; Espedal, Camilla; Støa-Aanensen, Nina Sasaki (Lecture Notes in Electrical Engineering;599, Chapter; Peer reviewed, 2020)In this paper, an experimental investigation of the thermal interruption performance of free-burning nitrogen arcs at 1 bar, 20 bar, and 40 bar filling pressures is reported. This work contributes to the fundamental ... -
Ultrahigh-Pressure Nitrogen Arcs Burning Inside Cylindrical Tubes
Abid, Fahim; Niayesh, Kaveh; Støa-Aanensen, Nina Sasaki (Journal article; Peer reviewed, 2018)When the pressure and temperature of a fluid exceed a critical point, the fluid enters into the supercritical (SC) region. In this region, the physical properties are believed to be in favor of a good current interruption ...
