Abstract:

Arc phenomena are discussed for the purposes of orientation and definition. Emphasis is placed on the distinction between low-intensity and high-intensity modes of arc operation. Following the preliminary discussion, the fundamental premises for the concept of a fluid transpiration arc are laid down. This concept relates to an arc discharge subject to the forced convection of a fluid medium, but differentiated from other systems of this type by the fact that the fluid is injected into the arc conduction zone via the anodic terminus through a porous anode structure. The postulated effectiveness criteria for this technique of arc heating require 1 that the average pore size be less than the anode fall space thickness, 2 that the transpiration surface be integrally congruent with the anodic discharge boundary, and 3 that the injected gas particle flux density have the same order of magnitude as the opposing drift electron flux density within the anode sheath region. A two-phase experimental program is described, the first being concerned with the validation of the basic concept and the second with a study of intrinsic characteristics. Author
