Hydrocarbon fuels detonation, equivalence

Since hydrogenous mixtures containing hydrocarbons can be used in engines, it is useful to study the detonation velocity in a combustible composite fuel in mixtures with air and oxygen. Such calculations for H2 + CH4 + O2 and H2 + CsHg + O2 were performed in [38] and are illustrated in Figs. 7.30 and 7.31 in detonation velocity (Z9)/equivalence ratio (0) coordinates. It is seen that the difference in detonation velocities between various composite triple mixtures and simple binary mixtures is insignificant [4, 5, 7, 12-59].
