BASIC RESEARCH ON GAS FLOWS THROUGH ELECTRIC ARCS, PHASE Ⅲ, STUDIES OF THE INLET REGION

摘要

Experimental and theoretical investigations dealing with interaction phenomena in the inlet or gas heating region of a segmented water-cooled constricted arc are reported.nA simple arc column theory including radiation is considerably refined to yield comprehensive scaling parameters for both the fully developed and the inlet regions of the arc. Extensive measurements on nitrogen, argon and hydrogen in both regions are listed and compared in detail with various aspects of the scaling theory.
