An analysis of the explosion limits of hydrogen-oxygen mixtures

Research output: Contribution to conference › Paper › peer-review

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.
