SINOPSIS
The aim of present research was to obtain data on the conditions of flame blowout in a laminar boundary layer with uniform injection of H2/N2 or H2/He fuel mixture through a horizontal porous plate into the air stream. This shows that the conditions of ignition and extinction of the flame in the boundary layer can be described by two quantities: dimensionless parameter and concentration of hydrogen in the fuel mixture. It turns out that the injection, corresponding to extinction, is inversely proportional to concentration of hydrogen.
