Two-dimensional fluid model for the inter-electrode region of a non-filtered vacuum arc
A simplified two-dimensional model which describes the inter-electrode region of a non-filtered vacuum arc with a cylindrical geometry is developed. The model includes elastic collisions and charge-exchange reactions between metallic particles and gas molecules, and also generation and recombination...
