Abstract
A computational analysis of the gas flow in a gas circuit breaker is presented in this paper. A structured grid with a high-order conservative overset method is used for an accurate flow analysis. In addition, this paper includes the modeling of the arc, radiation, and ablation of the nozzle. The results of the flow analysis are compared with the experimental data, showing good agreement with the experimental data.
