Porovnání vlastností obloukových výbojů s hybridní a vodní vírovou stabilizovací
 Jeništa, Jiří ; Bartlová, M. ; Aubrecht, V.
The paper deals with numerical modeling of the plasma torch electric arcs with water vortex stabilization and combined stabilization of arc by argon flow and water vortex. The axisymmetric model includes the arc discharge area between the near-cathode region and the outlet nozzle of the plasma torch. Thermal, electrical and fluid-dynamic characteristics as well as power losses of such arc has been studied for the range of currents 150-500 A. It was proved that addition of argon increases the plasma velocity but does not influence substantially the plasma temperature. The energy losses transferred radially from the arc by conduction and radiation range from 65 to 30 % of the input power. The amount of reabsorbed radiation, calculated by the partial characteristics method, divided to the total divergence of radiation flux is 35-26 % for hybrid torch and 25-16 % for water torch. The calculated velocities and temperatures show good agreement with experiments.
