Basic Research on Gas Flows Through Electric Arcs. Measurement Techniques and Analytical Procedures

摘要

Experimental and theoretical investigations dealing with interaction phenomena between gas flows and electric arcs in a Maecker-type, segmented, water-cooled arc column are reported. Specifically, the report details or references the measurement techniques and procedures used for measuring the various parameters of the arc column, including the power radiated per unit length and the temperature distribution, and presents experimental information including the results of downstream gas injection. In addition, the analytical procedures used to solve the direct arc column problem (finding the arcflow parameters, given the plasma properties) and the inverse arc column problem (finding the plasma properties, given the arc-flow parameters) for the asymptotic or fully-developed region, are presented.
