Study and generalization of the current-voltage and thermal characteristics of a dual-jet plasmatron
Abstract
The design, principles of operation, and characteristics of a dual-jet plasmatron are discussed. Particular attention is given to the current-voltage characteristic and the thermal fluxes to the electrodes. The axial and radial distributions of the arc intensity were measured, using an experimental version of the device. An arc model is proposed, and is used as basis to generalize the current-voltage characteristic and the thermal efficiency. The experimental voltage drop is found to agree within 20% with the values calculated from the expressions for the generalized current-voltage characteristic.
