Abstract

In the current work, experimental investigation of propagation and combustion of a inhomogeneous hydrogen-air mixture in a vertical channel were conducted. The average volume fraction of hydrogen varied from 10 to 30%. Data on the dynamics of hydrogen propagation along the channel height were obtained. In combustion experiments, data on the flame front propagation velocity and excess pressure were obtained. The effect of the mixture non-uniformity on combustion characteristics was estimated.
