Analysis of a plasma torch

, 1974
The phys. behavior of a plasma torch is described by a set of 5 equations with 5 variables. These equations make it possible to calc. the characteristic quantities of the plasma flow; i.e., degree of ionization, velocity, d., temp., and enthalpy. The equations are solved graphically. For comparison, the values as found by a computer are also given.
