Gas Dynamic

The results of studies of the dynamics of near-electrode processes in the initial phase of the spark are presented. discharge in air at atmospheric pressure in the tip – plane geometry. Near the surface of a flat After the breakdown of the cathode, regions with a size of about 50 μm and more were recorded with an increased electron concentration of (3–8)•10^19 cm^(– 3). Based on experimental data on erosion the effect of a discharge on the surface of a flat electrode and the associated gas-dynamic effects a physical model of near-electrode processes is proposed, based on which estimates are made gas dynamic parameters.

In high-pressure gas-jet emitters, the source of sound energy is kinetic energy of gas jet at supercritical pressure ratios between the working pressure and the atmospheric pressure. Under certain conditions, interaction of a supersonic jet with the resonator is accompanied by powerful self-excited oscillating process with the generation of acoustic waves into the environment and cavity resonator. A model of a self-excited oscillating process arising from the interaction of non-isobaric jet with semi-closed cylindrical cavities, allowing to distinguish typical elements of gas-dynamic structure of the forming flow, is considered. The physical pattern of the flow in the cavity of gas-jet emitter is discussed, and a study of the dependence of the characteristics of the self-excited oscillating process on the gas-dynamic and geometric parameters is performed.
