Özet

Detonation limit data obtained at ambient conditions for some aliphatic LNG/LPG constituents with oxygen and nitrogen (air) have been analyzed in search of a single critical parameter for detonation propagation. It was established that shock, rather than C-J reaction temperatures, provides a firm basis for marginal detonability prediction and that, furthermore, classical reaction mechanisms and relatively simple calculation methods can be used for their reliable evaluation. The result is used to formulate a criterion, for predicting composition limits to detonation. For the systems investigated, this criterion is accurate to within approximately 0.2% for fuel-lean and around 1% for fuel-rich mixtures.
