Pressure and concentration dependences of the autoignition temperature for normal butane + air mixtures in a closed vessel

Detailed chemical kinetic models for the low-temperature combustion of hydrocarbons with application to gasoline and diesel fuel surrogates

“…A last type of gas-phase apparatus, a spherical, stainless-steel vessel, has been used by Chandraratna and Griffiths (1994) [109] to investigate the conditions at which autoignition occurs in lean premixed n-butane + air mixtures. As reviewed by Pollard [47] and Griffiths [23], closed vessels have been much used before 1993 to study the low temperature oxidation of hydrocarbons and other gaseous organic compounds.…”

“…Simulations of the conditions under which autoignition occurs in lean premixed n-butane/air mixtures in a closed vessel were performed by the team of Griffiths using the models of Nancy and Livermore and compared to experimental data [109]. While the qualitative features are well accounted for, both models overpredict the autoignition temperatures at low concentrations of fuel [154].…”

Development of the Reduced Chemical Kinetic Mechanism for Combustion of H2/CO/C1–C4 Hydrocarbons

“…Several experimental as well as numerical studies on the chemical kinetics of n -butane/LPG oxidation based on autoignition and flame speed characteristics have been reported in the literature . The auto-ignition studies are conducted in closed vessels, − in open vessels to analyze autoignition characteristics in rapid compression machines (RCMs), − and in shock tubes. − Some other proposed methods for studying n -butane oxidation include flow reactors, static reactors, jet-stirred reactors, motor-powered engines, internal combustion engines, and homogeneous charge compression ignition engines. ,− Based on these studies, several chemical kinetic mechanisms for n -butane/LPG oxidation have been proposed for the real-time simulations for a wide range of operating conditions.…”

Low temperature n-butane oxidation skeletal mechanism, based on multilevel approach

“…Chandraratna and Griffiths investigated pressure and autoignition dependence of the autoignition temperature for normal butane in a closed vessel [1]. Rapid compression machines (RCM) are usually suitable for low-temperature, high-pressure conditions and have been used extensively for butane autoignition measurements [2][3][4].…”
