Abstract : The rate equations for the H2-O2 reaction have been integrated numerically under the conditions of steady flow in a Zeldovich-Doring-von Neumann detonation. A reaction scheme of 28 elementary reactions was used. The initial conditions covered the composition range from 16 to 92% H2 at pressures from 0.001 to 0.1 atm, 16 to 95 per cent at 1 atm, and 30 to 90 per cent at 10 atm. Comparison with the limited experimental data available shows that the computed induction times and reaction times are shorter than the experimental values. The reaction kinetic behavior of the H2-O2 system under conditions close to the isothermal branched-chain explosion limits is considered. The application to detonability limit calculations is discussed. (Author)
