Some reactions of oxygen atoms in flames (1965)
AuthorsMcEwan, M. J.show all
A flame can be regarded as a flowing reaction system in which the time scale in the usual reaction rate expressions is replaced by a scale of distance along the flame. Flames provide a convenient system in which to study the kinetics of high temperature gas reactions because wall reactions are absent and the relatively high linear velocities enables quite rapid reactions to be followed; e.g. radical recombination reactions at atmospheric pressure. The reactions to be discussed in this thesis have been studied using the techniques of flame photometry. From measurements of light emission or absorption as a function of flame temperature, composition and time from primary combustion, it is possible to make important deductions concerning the rates of elementary reactions in the burnt gas and the nature of the equilibria set-up among the components of the burnt gas.
