ABSTRACT

The flow arising in a volume-centered non-equilibrium discharge channel with propane and oxygen jet injection through an anode into supersonic airflow was investigated by the emission spectroscopy method. The experiments were carried out at M = 2, static pressure values of ~ 2.9 × 104 Pa (217 Torr) and 5.33 × 104 Pa (400 Torr), and discharge current in the range from 1 to ~ 1.85 A. Data on the composition and spatial distribution of the emission intensity of the reaction products, which appeared in the transformation process of the air–fuel mixture in the discharge region, were obtained. In particular, data on the CN, OH, and C2 emission intensity distributions and those for atomic hydrogen and oxygen are presented. The performed investigations allowed answering the question about the influence of the type of injecting components, methods of injection, and current values on the plasma chemical reaction intensities.
