Temperature factor effect on pulsating hydrogen combustion in a high-speed air flow

The results of a numerical study of the combustion of hydrogen jets injected into a high-speed air flow before a sudden channel expansion are presented. It is shown that under constant input conditions, a pulsating combustion mode is realized in the channel, which is maintained when the wall temperature increases from 300 to 900 K. An increase in the temperature factor leads to a decrease in the oscillation frequency and amplitude.
