Разработка кинетического механизма горения метано-водородного топлива

Abstract

Based on the Wang2018 model, an improved kinetic mechanism for the oxidation of methane-hydrogen mixtures, WangUPD, has been developed and validated using experimental data of normal flame speed (SL) obtained at the Heat Flux facility of Samara University and data from other studies. The mechanism is applied to calculate SL in a wide range of parameters: initial temperatures, pressures, fuel excess ratios (ϕ) and hydrogen content. Recommendations for modeling the combustion of methane-hydrogen fuels using the refined kinetics have been developed, which improves the accuracy of prediction of unsteady processes in the combustion chambers of gas turbine plants.
