Abstract

The essential factors governing the Z-shaped explosion limits of hydrogen-oxygen mixtures were studied using eigenvalue analysis. In particular, it is demonstrated that the wall destruction of the H and HO2 radicals is essential for the occurrence of the first and third limits, while that of the other radicals play secondary, quantitative roles for such limits. By assuming quasi-steady-state of O, OH and H2O2, an approximate, cubic equation for the explosion limits is obtained, from which explicit expressions governing the various explosion limits including the state of the loss of non-monotonicity were derived and discussed.
