Measurements of the flame propagation speed of H/F/O/He mixtures were carried out. The effect of the concentration of molecular hydrogen on the combustion rate has been studied. The lower concentration limit of hydrogen for the existence of combustion under the specified experimental conditions has been obtained. A model of chemical and gas-dynamic processes for calculating the combustion rate has been developed and the calculation results have been compared with the obtained experimental data. Additional processes are proposed, which can improve the coincidence of calculated and experimental data.
V. Ya. Agroskin (Wed,) studied this question.
