In adopting the DC arc plasma torch as a heat source of plasma tunnel, it is, first of all, important to know the nature of non-uniformity of the plasma flame in interpreting the data obtained in the test section. In this experiment, the authors pointed out that the non-uniformity occurred even in the domain equivalent to static arc, and that it seemed, therefore, doubtful to use the anode nozzle as a supersonic nozzle. Next, it is observed that, in the domain in which cyclic voltage fluctuation is present, the nature of the fluctuation is analogous to the vibration of string with both end being fixed, and from the energy equilibrium consideration, the desirable operating condition of torch is proposed. Some comments are made on the electrode failure.
