【摘要】 <正> Influence of the shock wave on the turbulence in a supersonic nozzle was investigatedfor a SF6 puffer circuit breaker interruption process. Turbulence is enlarged through the shockwave. Baroclinic generation of vortex causes flow separation and broadening of the arc crosssection. V-I characteristics are slightly modified due to the shock wave’s influence.
