Flame acceleration and transition to detonation in channels
Conference
·
OSTI ID:6143459
Experimental results are reported for combustion of pre-mixed H/sub 2/-air mixtures in a 136 m/sup 3/ channel and a 1:12.6 linear scale model. Test variables include H/sub 2/-air equivalence ratio, obstacles and degree of transverse venting. The results show that flame acceleration is increased by sensitive mixtures, presence of obstacles, large scales, and insufficient venting. The results also support the hypothesis that deflagration to detonation transition (DDT) can occur if the ratio of detonation cell width to channel width is less than a critical value, provided that the flame speed prior to transition has approached the isobaric sound speed.
