| Abstract | The 0D and 1D aproaches for lean flammability limit determination are presented for hydrogen-air mixture. Results, obtained with the use of two methods revealed the consistency of 1D approach rather than 0D. It is shown that the ignition of lean mixtures is unstable towards gasdynamic effects evolving on the scales of ignition zone. The other part of the paper investigates the concentration limits of flame propagation and demonstrates that the addition of the spatial domain with non-uniform concentration distribution to the uniform one could expand the concentration limits of flame propagation. |
