Hydrodynamic model for a vacuum arc operated with background gas: Theory and experimental validation

Mostrar todas las versiones(3)

A stationary, one-dimensional fluid model is presented to describe the interelectrode region of a nonfiltered vacuum arc operated with a background gas. The model includes the electron energy equation and the main elastic and inelastic atomic processes among metallic ions, electrons, and gas particl...
