EXTINCTION AND AUTOIGNITION OF n-HEPTANE IN COUNTERFLOW CONFIGURATION
A study was performed to elucidate the mechanisms of extinction and autoignition of n-heptane in strained laminar flows under non-premixed conditions. A previously developed detailed mechanism made up of 2540 reversible elementary reactions among 556 species was the starting point for the study. The detailed mechanism was previously used to calculate ignition delay times in homogeneous reactors...
متن کاملAutoignition of Binary Fuel Blends of n-Butanol and n-Heptane in a Rapid Compression Machine
Autoignition of binary blends of n-butanol and n-heptane was studied in a rapid compression machine at an equivalence ratio of 0.4 and a compressed pressure of 20 bar with the compressed temperature varying from 700 K to 907 K. Within the temperature range covered in this study, no cool flame or negative temperature coefficient behavior was observed for neat n-butanol. With the presence of n-he...
متن کاملEffects of strain rate on high-pressure nonpremixed n-heptane autoignition in counterflow
The effect of steady strain on the transient autoignition of n-heptane at high pressures is studied numerically with detailed chemistry and transport in a counterflow configuration. Skeletal and reduced n-heptane mechanisms are developed and validated against experiments over a range of pressure and stoichiometries. Two configurations are investigated using the skeletal mechanism. First, the ef...
متن کاملOlefin Chemistry in a Premixed n-Heptane Flame
ion reactions reach their maximum rates, however, in the high-temperature region, where thermal decomposition reactions are also most active. Formation and Consumption of Other Olefins. Despite the model-dependent differences in reactions of heptene isomers, the chemistry of other olefins is very similar for all three mechanisms, especially for larger olefins. Reactions that involve oxygenated ...
متن کاملAdaptation and application of the In Situ Adaptive Tabulation (ISAT) procedure to reacting flow calculations with complex surface chemistry
In this article, the in situ Adaptive Tabulation (ISAT) procedure, originally developed for the efficient computation of homogeneous reactions in chemically reacting flows, is adapted and demonstrated for reacting flow computations with complex heterogeneous (or surface) reactions. The treatment of heterogeneous reactionswithin a reacting flow calculation requires solution of a set of nonlinear...
