Annual report of combustion chemical kinetics research 2013

Abstract：Combustion provides over 80% energy supply for modern society， and plays irreplaceable roles in core fields such as industry， transportation and national defense. At present， combustion studies are moving from macroscale phenomenology to microscale turbulent simulation and combustion chemical kinetics， focusing on understanding the relationships of fuel compositions， molecule structures and combustion conditions with combustion efficiencies and pollutant emissions. In particular， the studies of combustion chemical kinetics of jet fuels and biofuels are very significant for national security and energy sustainability. In this year， our research focuses on the applications of vacuum ultraviolet （VUV） photoionization method in combustion research， combustion chemical kinetics of important components in jet fuels， combustion chemical kinetics of biofuels， and so on. For the first topic， we applied the VUV photoionization method in various combustion research fields， such as atmospheric pressure premixed flame studies， coal pyrolysis， biomass pyrolysis， and so on. We also published an invited paper on Proceedings of the Combustion Institute which is the most prestigious combustion journal， introducing our pioneering development of the synchrotron-based combustion diagnostic tool and applications of it in various fields of combustion research. In studies of combustion chemical kinetics of important components of jet fuels， we also performed an experimental and kinetic modeling investigation on the pyrolysis and oxidation of methylcyclohexane. In studies of combustion chemical kinetics of hot biofuels， we investigated the pyrolysis and oxidation of sec-butanol， the coflow diffusion n-butanol/methane flames and the low-pressure pyrolysis of methyl propionate. In 2013， we published over 37 papers on famous SCI journals in related fields， such as Proceedings of the Combustion Institute， Combustion and Flame， Journal of the American Chemical Society， Physical Review Letters， Review of Scientific Instruments， Energy & Fuels， Journal of Chemical Physics， Journal of Physical Chemistry C， Journal of Physical Chemistry C and Optical Letters， and finished the planned research targets.
