“…Taking into account the multistage nature of physical and chemical processes, it is advisable to study the efficiency of methane combustion in a HOF using a facility with oxidative reactions realization in a constant cross-section channel [53,54]. In this study, the tests were carried out on an experimental facility, the scheme of which is shown in Figure 1.…”

The article presents the experimental study analysis results of the methane combustion efficiency in a high-enthalpy oxygen-containing flow (HOF) inside of constant cross-section channel, finite along the length. The range of initial HOF enthalpies was considered from 350 to 700 kJ/kg. The regularities of the HOF initial enthalpy influence on the methane combustion efficiency were obtained. The values of the fuel excess coefficient under which the maximum coefficients of methane combustion completeness in the HOF are realized were determined. The data obtained indicate the realization of transitional diffusion-kinetic modes of methane combustion and make it possible to assess the factors limiting the combustion process.
