Aerodynamic stabilization of gaseous discharges
Abstract
This report covers some aspects of the formulation of the stabilization problem by aerodynamic means. Results of experimental work are not included but are referred to in appropriate places. The classical solution for ambipolar diffusion in tne positive column of the glow discharge must be extended to reflect
the influence of current and pressure. The influence of current is given by tne inclusion of appropriate energy equations and the pressure influence by tne addition of two-body recombination. It was found that, from dimensional
analysis, the characteristic lengths for ambipolar and heat diffusion forhelium do not match. A re-formulation of the problem is thus necessary. The recombination term does not change the eigenvalue nature of the diffussion
equation except at the stationary or local equilibrium limit.
