Measuring of mean electrical conductivity of a plasma volume in hot anode area of DC arc plasma torches.
Original language description
We focused on measurement of electrical conductivity of the plasma in the anode area of a hybrid plasma torch. We measured plasma effective electrical conductivity in the anode area for various values of electric current, ambient pressure and argon flow rate, and for two configurations of the anode position. Finally, in some case, we compared our measured electrical conductivity data with model electrical conductivity data from computer simulations. We also found the corresponding plasma temperatures and compared them with the plasma temperatures measured spectroscopically. In both cases, there is a good agreement between them. Our results provide missing experimental data on the electrical conductivity of the plasma in the hot anode area, suitable for comparisons with computer simulations. The method can be used also for other plasma torches with an external anode. Moreover, the idea of the method can be further improved in both, theoretical exactness and experimental accuracyn
