Perturbed Arcs in Turbulent Axial Gas Flow II. Fluctuating Local Properties

Abstract

As a continuation of the research described in Pt. I, local quantities are studied experimentally by electrostatic wall probing, time resolving shadowgraphy and radial luminosity profile scanning of arcs in turbulent axial gas flow. Turbulency of the gas coolant and thermal sheath properties are discussed as well as the consequenciee of the gathered knowledge to theoretical modelling.
