    • A comprehensive experimental and improved kinetic modeling study on the pyrolysis and oxidation of propyne 

      Panigrahy, Snehasish; Liang, Jinhu; Nagaraja, Shashank S.; Zuo, Zhaohong; Kim, Gihun; Dong, Shijun; Kukkadapu, Goutham; Pitz, William J.; Vasu, Subith S.; Curran, Henry J. (Elsevier, 2020-09-15)
      To improve our understanding of the combustion characteristics of propyne, new experimental data for ignition delay times (IDTs), pyrolysis speciation profiles and flame speed measurements are presented in this study. IDTs ...

    • Cyclopentane combustion. Part II. Ignition delay measurements and mechanism validation 

      Al Rashidi, Mariam J.; Mármol, Juan C.; Banyon, Colin; Sajid, Muhammad B.; Mehl, Marco; Pitz, William J.; Mohamed, Samah; Alfazazi, Adamu; Lu, Tianfeng; Curran, Henry J.; Farooq, Aamir; Sarathy, S. Mani (Elsevier, 2017-06-12)
      This study reports cyclopentane ignition delay measurements over a wide range of conditions. The measurements were obtained using two shock tubes and a rapid compression machine, and were used to test a detailed low- and ...

    • Development of multipurpose skeletal core combustion chemical kinetic mechanisms 

      Wang, Quan-De; Panigrahy, Snehasish; Yang, Shiyou; Martinez, Sergio; Liang, Jinhu; Curran, Henry J. (American Chemical Society, 2021-03-25)
      Core combustion kinetic mechanisms for small C0¿C4 fuel molecules are not only of the utmost importance in understanding their individual combustion properties but are also the foundation for the development of kinetic ...

    • An experimental and detailed kinetic modeling study of the pyrolysis and oxidation of allene and propyne over a wide range of conditions 

      Panigrahy, Snehasish; Liang, Jinhu; Kumer Ghosh, Manik; Wang, Quan-De; Zuo, Zhaohong; Nagaraja, Shashank; El-SaborMohamed, A. Abd; Kim, Gihun; Vasu, Subith S.; Curran, Henry J. (Elsevier, 2021-07-27)
      Allene and propyne are important intermediates in the pyrolysis and oxidation of higher hydrocarbon fuels, and they are also a major source of propargyl radical formation, which can recombine into different C 6 H 6 isomers ...

    • Experimental and kinetic modeling study of 3-Methyl-2-butenol (Prenol) oxidation 

      Lokachari, Nitin; Wagnon, Scott W.; Kukkadapu, Goutham; Pitz, William J.; Curran, Henry J. (American Chemical Society, 2021-08-19)
      Longer chain alcohols with 4–5 carbon atoms are attractive alternative fuels as they can be derived from biological sources and since their combustion leads to lower exhaust gas levels of NOx and soot compared to commercial ...

    • An experimental and kinetic modeling study of the auto-ignition of natural gas blends containing C1–C7 alkanes 

      Mohamed, Ahmed Abd El-Sabor; Panigrahy, Snehasish; Sahu, Amrit Bikram; Bourque, Gilles; Curran, Henry J. (Elsevier, 2020-07-16)
      Ignition delay time measurements for multi-component natural gas mixtures were carried out using a rapid compression machine at conditions relevant to gas turbine operation, at equivalence ratios of 0.5–2.0 in ‘air’ in the ...

    • An experimental and kinetic modeling study of the pyrolysis and oxidation of n-C-3-C-5 aldehydes in shock tubes 

      Pellucci, Matteo; Somers, Kieran P.; Yasunaga, Kenji; Burke, Ultan; Alessio, Frassoldati; Ranzi, Eliseo; Curran, Henry J.; Faravelli, Tiziano (Elsevier ScienceDirect, 2015-08-24)
      Due to the increasing interest in the use of biofuels for energy production, it is of great importance to better understand the combustion and thermal decomposition characteristics of species such as aldehydes. These are ...

    • An ignition delay time and chemical kinetic modeling study of the pentane isomers
