Аннотация на английском языке
The ignition of lean hydrogen-air mixtures behind reflected shock waves at the temperature range of 902–1630 K and the pressure of 1 atm is studied experimentally and numerically. For the first time, reliable experimental data is obtained for temperatures below 1000 K, directly in the zone of change in the dominance of chain branching and chain termination reactions, which influence the formation of the ignition delay value. Expressions are formulated for ignition delay in two temperature intervals below and above 970–980 K, and the corresponding activation energy values are determined. Good agreement between the experimentally observed and calculated ignition delay values is demonstrated. The local sensitivity analysis allowed us to reduce the kinetic mechanism.
