Effects of Fast Elongation on Switching Arcs Characteristics in Fast Air Switches
Kadivar, Ali; Niayesh, Kaveh (Journal article; Peer reviewed, 2020)This paper is devoted to investigating the effects of high-speed elongation of arcs inside ultra-fast switches (ucontact≈ 5–80 m/s), through a 2-D time-dependent model, in Cartesian coordinates. Two air arcs in series, one ... -
Metal vapor content of an electric arc initiated by exploding wire in a model N2 circuit breaker: simulation and experiment
Kadivar, Ali; Niayesh, Kaveh; Abid, Fahim (Peer reviewed; Journal article, 2020)A conductive wire can explode by rapidly heating it to vaporization temperature by flowing a current through it. This process is utilized to generate high-temperature high-density plasmas. The temperature and pressure ... -
Two-way Interaction between Switching Arc and Solid Surfaces: Distribution of Ablated contact and Nozzle Materials
Kadivar, Ali; Niayesh, Kaveh (Journal article; Peer reviewed, 2019)This paper is devoted to two-way plasma-surface interactions by investigating how the plasma arc ablates the nozzle and contacts and how the distribution of ablated materials changes the plasma parameters. For this ...
