Аннотация

The results of the experimental study and numerical simulations of the boundary layer with H2/N2 injection and combustion are presented. The data on the flame-off conditions, depending on the flow velocity, the intensity of injection and thermal properties of the fuel are shown. A diagram of stable combustion and extinction is given in dimensionless coordinates as the correlation of nondimensional fuel mixture blowing rate and the degree of hydrogen dilution. It was observed that the hydrogen flame-off conditions in laminar or turbulent boundary layer flow are the same. The analytical evaluation based on a Schwab-Zel’dovich model was obtained which made possible the generalization of the results, allow to evaluate the influence the flame-off conditions in different fuel mixtures: H2/N2, H2/CO2 and H2/hydrocarbons. The peculiarities of flow near the flame leading age are described.
