Ignition Delay Time Measurements and Modeling of n-Pentane and iso-Pentane at Elevated Pressures Conference Paper uri icon

abstract

  • Ignition delay times of n-pentane and iso-pentane in real fuel-air mixtures with oxygen and nitrogen were measured in a shock tube and a rapid compression machine (RCM). Data were then used to improve the current kinetics model. All results were obtained at an equivalence ratio of 1.0 and at pressures near 1, 10, and 20 atm for the shock tube and 10 and 20 atm for the RCM. Experimental temperatures ranged from 641 to 1410 K. When compared to the chemical kinetics model, in general, ignition delay times were well predicted for n-pentane, while iso-pentane predictions were longer than experimental values in the negative temperature coefficient region. To the authors' knowledge, this study covers conditions not yet present in the literature and will expand fundamental knowledge of n-pentane and iso-pentane combustion kinetics. 2013 by the authors.
