Effects of Mechanical and Thermal Electrode Properties on the Behavior of the Fluid Transpiration Arc
Abstract
A triple cathode, single anode arc assembly, designed to produce a symmetrical free-burning plasma jet, was completed and placed into operation. A second arc assembly with a single gas-injection cathode, was also constructed for the double purpose of testing porous anodes and accelerating the acquisition of diagnostic data. Diagnostic instrumentation was developed, based on high speed transient probing with miniature sensing elements. Work was carried forward on the development of porous anodes. Diagnostic experiments include measurements of arc terminal characteristics, current density distribution, temperature variations, potential distribution, plasma luminosity distribution and calorimetry experiments. The influence of forced convection into the negative column near the cathode was separately investigated. A two-dimensional computer analysis of transpiration cooling of the porous anode was worked out.
