Abstract

A comprehensive numerical and experimental study of the flame flashback boundaries in combustion of a premixed methane–hydrogen flame in a vortex burner with flow swirling and also in a model combustor, which is a prototype of low-emission combustors with fuel premixing, is performed. Based on the results of the study, recommendations are given, which allow the flame flashback to be determined with an error smaller than \(\pm\) 5%. These results can be used to increase the accuracy of determining the flame flashback in combustion of the methane–hydrogen fuel at the stage of preliminary design of combustors for aviation gas-turbine engines and propulsion facilities.
