The statement of problem is based on experimental investigations, which were performed recently in Technical University of Munich. Modeling is implemented in two-dimensional statement with using detailed kinetics model of hydrogen combustion. The presence of deficiency propagation velocity of the detonation wave (DW) in a channel filled a mixture with transverse concentration gradient compared with one in the channel filled with a homogeneous mixture at the same average volumetric hydrogen concentration is consistent with the experimental data. The special mode of detonation propagation for channel filled hydrogen-air mixture with averaged volumetric concentration of hydrogen 40% and volumetric concentration of hydrogen 64.6% at the upper wall of the channel is revealed. In that mode, there is strong periodically arising transverse wave, which burns rich mixture at the upper part of the channel.
