An analytical approximation for high-temperature autoignition times of higher alkanes

It is shown that, above about 1000 K, ignition delay times for propane and all higher alkanes, as well as for a number of other fuels, can be calculated well by employing rate parameters of only three types of elementary steps, namely C{sub m}H{sub n} + HO{sub 2} {yields} C{sub m}H{sub n-1} + H{sub 2}O{sub 2}, H{sub 2}O{sub 2} + M{yields}2OH + M and 2HO{sub 2} {yields} H{sub 2}O{sub 2} + O{sub 2}, only the first of which is fuel specific, the...
