摘要：

Turbulence plays a key role in several physical processes related to the interruption of current in a gas circuit breaker (GCB). In this paper we study one aspect, namely turbulent gas mixing in the heating volume of a small-scale 3D GCB model. Mixing is observed using a shadowgraphy setup; postprocessing extracts information on the time-varying velocity field. Discharges with two different current amplitudes were studied and their repeatability investigated. A measure of mixing completeness, the largest vortex area, was investigated. The experiments reported upon in this paper were done in air at atmospheric pressure.
