INFLUENCE OF THE SIZE FACTOR ON THE ACCURACY
OF VOLT-AMPERE CHARACTERISTICS OF A VORTEX
ELECTRIC-ARC PLASMATRON WITH TUBULAR ELECTRODES

Statistical methods of analysis are used to study
the influence of a change in the electrode diameter
on the accuracy of the volt-ampere characteristics
(VACs) of a vortex electric-arc plasmatron operating
with technical nitrogen. It is shown that when each
initial parameter is allowed for separately and the
VACs are represented by an empirical formula, the
influence of a change in the diameter is insignificant.
When all the initial parameters are allowed for
simultaneously in one dominant criterion in the case of
approximation of VACs by a generalized expression, the
effect of the size factor proves to be substantial.
