Diffuse and spot mode of cathode arc attachments in a at mospheric magnetically rotating argon arc

摘要: To understand the arc and thermal plasmas, a wide range of numerical simulations based n computational fluid dynamics coupled with electromagnetics have been carried out. Although LTE models are proved successful to predict plasma temperature, deviations from experimentally observed, especially around fringe1. Furthermore, interaction cathode surface plays key role in whole discharge processe2, 3. research phenomena thermionic, model including cathode, near-cathode layer column is needed.
