Hydrogen combustion under conditions of a high-temperature supersonic flow

Abstract

Some results of studying the combustion of hydrogen in a high-velocity air flow at stagnation temperatures below 3000 K are given. Flame shape and combustion zone length change at temperatures above 2000–2200 K due to deterioration in the fuel–oxidizer mixing process. It has been shown that dissociation processes have an effect on the process of hydrogen combustion at a high temperature. In experiments, they can be detected by a change in the intensity of radiation from the intermediate ОН* radical.
