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 ... -
An experimental and kinetic modeling study of the ignition delay characteristics of binary blends of ethane/propane and ethylene/propane in multiple shock tubes and rapid compression machines over a wide range of temperature, pressure, equivalence ratio, and dilution
Martinez, Sergio; Baigmohammadi, Mohammadreza; Patel, Vaibhav; Panigrahy, Snehasish; Sahu, Amrit B.; Nagaraja, Shashank S.; Ramalingam, Ajoy; Mohamed, A. Abd El-Sabor; Somers, Kieran P.; Heufer, Karl A.; Pekalski, Andrzej; Curran, Henry J. (Elsevier, 2021-03-02)In this work, the ignition delay time characteristics of C2 – C3 binary blends of gaseous hydrocarbons including ethylene/propane and ethane/propane are studied over a wide range of temperatures (750 – 2000 K), pressures ... -
A fundamental study on the pyrolysis of hydrocarbons
Nagaraja, Shashank S.; Sahu, Amrit B.; Panigrahy, Snehasish; Curran, Henry J. (Elsevier, 2021-07-10)A newly developed detailed chemical kinetic mechanism, NUIGMech1.1, is used to study the pyrolysis of C1 ¿ C7 hydrocarbons at a constant initial fuel concentration in the temperature range 900 ¿ 2000 K. We observe that, ... -

(Elsevier, 2020-06-27)A single-pulse shock tube study of the pyrolysis of 2% C-2 - C-6 1-alkenes is presented at 2 bar in the tem-perature range 900-1800 K in the current study. Reactant, intermediate and product species are obtained and ... -
Hierarchical study of the reactions of hydrogen atoms with alkenes: A theoretical study of the reactions of hydrogen atoms with C2–C4 alkenes
Power, Jennifer; Somers, Kieran P.; Nagaraja, Shashank S.; Curran, Henry J. (American Chemical Society, 2021-06-08)The present study complements our previous studies of the reactions of hydrogen atoms with C5 alkene species including 1- and 2-pentene and the branched isomers (2-methyl-1-butene, 2-methyl-2-butene, and 3-methyl-1-butene), ... -
A pyrolysis study of allylic hydrocarbon fuels
Nagaraja, Shashank S.; Kukkadapu, Goutham; Panigrahy, Snehasish; Liang, Jinhu; Lu, Haitao; Pitz, William J.; Curran, Henry J. (Wiley, 2020-08-17)The pyrolysis of selected C3 C5 allylic hydrocarbons has been studied using a single-pulse shock tube. A new single-pulse shock tube has been designed and constructed by recommissioning an existing conventional shock ... -
