Abstract: AbstractThis paper addresses homogeneous ignition of hydrogen-oxygen mixtures when the initial conditions of temperature and pressure place the system below the crossover temperature associated with the second explosion limit.A three-step reduced mechanism involving H 2 , O 2 , H 2 O, H 2 O 2 and HO 2 , derived previously from a skeletal mechanism of eight elementary steps by assuming O, OH and H to follow steady state, is seen to describe accurately the associated thermal explosion. At sufficiently low tempe…
