| Popis: | Deflagration to detonation transitions (DDT) of methane, methane ethane , ethane, propane, and butane in mixtures with increasing dilution of nitrogen have been studied in a smooth 2″ id detonation tube with a length/diameter ratio of 220. The results obtained demonstrate the presence of two regimes of DDT depending on the reactivity of the mixture. The first regime displays rapid acceleration to a stable detonation, while the second regime contains a quasistable, strong deflagration of rapidly increasing duration with decreasing mixture reactivity. It is established that the order of DDT under the conditions employed follows the order of autoignition temperatures for the fuels considered. The conditional use of transition parameters for estimates of relative detonabilities based on a qualitative similarity between induction times and times to transition is demonstrated to hold only for the first transition regime. |
