Zur theoretischen Beschreibung zylindersymmetrischer modulierter Lichtbögen

In this paper properties and dependence upon parameters of electric d.c. arcs with a.c. components are investigated. Expanding older theories analytical solutions of the basic equations of the one fluid modell are given for this problem using an extended Bessel modell and numerical calculations are made. Thereby the exact equations determine dependences upon parameters in limiting cases. The obtained results are compared with experimental data given in literature. The good agreement shows the validity of the applied methods.
